+-   Verify that "allowas-in" feature works per address-family/VRF
+    'basis and doesn't impact the other AFIs.
+-   Verify that the if number of occurrences of AS number in path is
+    'more than the configured allowas-in value then we do not accept
+    'the route.
+-   Verify that when we advertise a network, learned from the same AS
+    'via allowas-in command, to an iBGP neighbor we see multiple
+    'occurrences.
+-   Verify that when we advertise a network, learned from the same AS

+
+1. z1 announces 192.168.255.254/32 to y2, y3.
+2. y2 and y3 tags this prefix at ingress with appropriate
+communities 65004:2 (y2) and 65004:3 (y3).
+3. x1 filters all communities at the egress to c1.
+4. Shutdown the link between y1 and y2.
+5. y1 will generate a BGP UPDATE message regarding the next-hop change.
+6. x1 will generate a BGP UPDATE message regarding community change.
+
+To avoid sending duplicate BGP UPDATE messages we should make sure
+we send only actual route updates. In this example, x1 will skip
+BGP UPDATE to c1 because the actual route is the same
+(filtered communities - nothing changes).

+Following tests are covered to test ecmp functionality on EBGP.
+1. Verify routes installed as per maximum-paths configuration (8/16/32)
+2. Disable/Shut selected paths nexthops and verify other next are installed in
+   the RIB of DUT. Enable interfaces and verify RIB count.
+3. Verify BGP table and RIB in DUT after clear BGP routes and neighbors.
+4. Verify routes are cleared from BGP and RIB table of DUT when
+   redistribute static configuration is removed.
+5. Shut BGP neighbors one by one and verify BGP and routing table updated
+   accordingly in DUT
+6. Delete static routes and verify routers are cleared from BGP table and RIB
+   of DUT.
+7. Verify routes are cleared from BGP and RIB table of DUT when advertise
+   network configuration is removed.

+Following tests are covered to test ecmp functionality on EBGP.
+1. Verify routes installed as per maximum-paths configuration (8/16/32)
+2. Disable/Shut selected paths nexthops and verify other next are installed in
+   the RIB of DUT. Enable interfaces and verify RIB count.
+3. Verify BGP table and RIB in DUT after clear BGP routes and neighbors.
+4. Verify routes are cleared from BGP and RIB table of DUT when
+   redistribute static configuration is removed.
+5. Shut BGP neighbors one by one and verify BGP and routing table updated
+   accordingly in DUT
+6. Delete static routes and verify routers are cleared from BGP table and RIB
+   of DUT.
+7. Verify routes are cleared from BGP and RIB table of DUT when advertise
+   network configuration is removed.

+
+    Host1 is connected to PE1 and host2 is connected to PE2
+    Host1 and PE1 have IPv4/v6 BGP sessions.
+    PE1 and PE2 gave EVPN session.
+    Host1 advertises IPv4/v6 prefixes to PE1.
+    PE1 advertises these prefixes to PE2 as EVPN type-5 routes.
+    Gateway IP for these EVPN type-5 routes is host1 IP.
+    Host1 MAC/IP is advertised by PE1 as EVPN type-2 route
+
+Following testcases are covered:
+TC_1:
+Check BGP and zebra states for above topology at PE1 and PE2.
+
+TC_2:
+Stop advertising prefixes from host1. It should withdraw type-5 routes. Check states at PE1 and PE2
+Advertise the prefixes again. Check states.
+
+TC_3:
+Shut down VxLAN interface at PE1. This should withdraw type-2 routes. Check states at PE1 and PE2.
+Enable VxLAN interface again. Check states.

+Following tests are covered to test BGP Graceful Restart functionality.
+Basic Common Test steps for all the test case below :
+- Create topology (setup module)
+  Creating 2 routers topology, r1, r2 in IBGP
+- Bring up topology
+- Verify for bgp to converge
+- Configure BGP Garceful Restart on both the routers.
+
+1. Transition from Peer-level helper to Global Restarting
+2. Transition from Peer-level helper to Global inherit helper
+3. Transition from Peer-level restarting to Global inherit helper
+4. Default GR functional mode is Helper.
+5. Verify that the restarting node sets "R" bit while sending the
+   BGP open messages after the node restart, only if GR is enabled.
+6. Verify if restarting node resets R bit in BGP open message
+   during normal BGP session flaps as well, even when GR restarting
+   mode is enabled. Here link flap happen due to interface UP/DOWN.
+7. Verify if restarting node resets R bit in BGP
+   open message during normal BGP session flaps when GR is disabled.
+8. Verify that restarting nodes set "F" bit while sending
+   the BGP open messages after it restarts, only when BGP GR is enabled.
+9. Verify that only GR helper routers keep the stale
+   route entries, not any GR disabled router.
+10. Verify that GR helper routers keeps all the routes received
+    from restarting node if both the routers are configured as
+    GR restarting node.
+11. Verify that GR helper routers delete all the routes
+    received from a node if both the routers are configured as GR
+    helper node.
+12. After BGP neighborship is established and GR capability is exchanged,
+    transition restarting router to disabled state and vice versa.
+13. After BGP neighborship is established and GR capability is exchanged,
+    transition restarting router to disabled state and vice versa.
+14. Verify that restarting nodes reset "F" bit while sending
+    the BGP open messages after it's restarts, when BGP GR is **NOT** enabled.
+15. Verify that only GR helper routers keep the stale
+    route entries, not any GR disabled router.
+16. Transition from Global Restarting to Disable and then Global
+    Disable to Restarting.
+17. Transition from Global Helper to Disable and then Global
+    Disable to Helper.
+18. Transition from Global Restart to Helper and then Global
+    Helper to Restart, Global Mode : GR Restarting
+    PerPeer Mode :  GR Helper
+    GR Mode effective : GR Helper
+19. Transition from Peer-level helper to Global Restarting,
+    Global Mode : GR Restarting
+    PerPeer Mode :  GR Restarting
+    GR Mode effective : GR Restarting
+20. Transition from Peer-level restart to Global Restart
+    Global Mode : GR Restarting
+    PerPeer Mode :  GR Restarting
+    GR Mode effective : GR Restarting
+21. Transition from Peer-level disabled to Global Restart
+    Global Mode : GR Restarting
+    PerPeer Mode : GR Disabled
+    GR Mode effective : GR Disabled
+22. Peer-level inherit from Global Restarting
+    Global Mode : GR Restart
+    PerPeer Mode :  None
+    GR Mode effective : GR Restart
+23. Transition from Peer-level disable to Global inherit helper
+    Global Mode : None
+    PerPeer Mode :  GR Disable
+    GR Mode effective : GR Disable
+
+These tests have been broken up into 4 sub python scripts because
+the totality of this run was fairly significant.

+Following tests are covered to test BGP Graceful Restart functionality.
+Basic Common Test steps for all the test case below :
+- Create topology (setup module)
+  Creating 2 routers topology, r1, r2 in IBGP
+- Bring up topology
+- Verify for bgp to converge
+- Configure BGP Garceful Restart on both the routers.
+
+1. Transition from Peer-level helper to Global Restarting
+2. Transition from Peer-level helper to Global inherit helper
+3. Transition from Peer-level restarting to Global inherit helper
+4. Default GR functional mode is Helper.
+5. Verify that the restarting node sets "R" bit while sending the
+   BGP open messages after the node restart, only if GR is enabled.
+6. Verify if restarting node resets R bit in BGP open message
+   during normal BGP session flaps as well, even when GR restarting
+   mode is enabled. Here link flap happen due to interface UP/DOWN.
+7. Verify if restarting node resets R bit in BGP
+   open message during normal BGP session flaps when GR is disabled.
+8. Verify that restarting nodes set "F" bit while sending
+   the BGP open messages after it restarts, only when BGP GR is enabled.
+9. Verify that only GR helper routers keep the stale
+   route entries, not any GR disabled router.
+10. Verify that GR helper routers keeps all the routes received
+    from restarting node if both the routers are configured as
+    GR restarting node.
+11. Verify that GR helper routers delete all the routes
+    received from a node if both the routers are configured as GR
+    helper node.
+12. After BGP neighborship is established and GR capability is exchanged,
+    transition restarting router to disabled state and vice versa.
+13. After BGP neighborship is established and GR capability is exchanged,
+    transition restarting router to disabled state and vice versa.
+14. Verify that restarting nodes reset "F" bit while sending
+    the BGP open messages after it's restarts, when BGP GR is **NOT** enabled.
+15. Verify that only GR helper routers keep the stale
+    route entries, not any GR disabled router.
+16. Transition from Global Restarting to Disable and then Global
+    Disable to Restarting.
+17. Transition from Global Helper to Disable and then Global
+    Disable to Helper.
+18. Transition from Global Restart to Helper and then Global
+    Helper to Restart, Global Mode : GR Restarting
+    PerPeer Mode :  GR Helper
+    GR Mode effective : GR Helper
+19. Transition from Peer-level helper to Global Restarting,
+    Global Mode : GR Restarting
+    PerPeer Mode :  GR Restarting
+    GR Mode effective : GR Restarting
+20. Transition from Peer-level restart to Global Restart
+    Global Mode : GR Restarting
+    PerPeer Mode :  GR Restarting
+    GR Mode effective : GR Restarting
+21. Transition from Peer-level disabled to Global Restart
+    Global Mode : GR Restarting
+    PerPeer Mode : GR Disabled
+    GR Mode effective : GR Disabled
+22. Peer-level inherit from Global Restarting
+    Global Mode : GR Restart
+    PerPeer Mode :  None
+    GR Mode effective : GR Restart
+23. Transition from Peer-level disable to Global inherit helper
+    Global Mode : None
+    PerPeer Mode :  GR Disable
+    GR Mode effective : GR Disable
+
+These tests have been broken up into 4 sub python scripts because
+the totality of this run was fairly significant.

+Following tests are covered to test BGP Graceful Restart functionality.
+Basic Common Test steps for all the test case below :
+- Create topology (setup module)
+  Creating 2 routers topology, r1, r2 in IBGP
+- Bring up topology
+- Verify for bgp to converge
+- Configure BGP Garceful Restart on both the routers.
+
+1. Transition from Peer-level helper to Global Restarting
+2. Transition from Peer-level helper to Global inherit helper
+3. Transition from Peer-level restarting to Global inherit helper
+4. Default GR functional mode is Helper.
+5. Verify that the restarting node sets "R" bit while sending the
+   BGP open messages after the node restart, only if GR is enabled.
+6. Verify if restarting node resets R bit in BGP open message
+   during normal BGP session flaps as well, even when GR restarting
+   mode is enabled. Here link flap happen due to interface UP/DOWN.
+7. Verify if restarting node resets R bit in BGP
+   open message during normal BGP session flaps when GR is disabled.
+8. Verify that restarting nodes set "F" bit while sending
+   the BGP open messages after it restarts, only when BGP GR is enabled.
+9. Verify that only GR helper routers keep the stale
+   route entries, not any GR disabled router.
+10. Verify that GR helper routers keeps all the routes received
+    from restarting node if both the routers are configured as
+    GR restarting node.
+11. Verify that GR helper routers delete all the routes
+    received from a node if both the routers are configured as GR
+    helper node.
+12. After BGP neighborship is established and GR capability is exchanged,
+    transition restarting router to disabled state and vice versa.
+13. After BGP neighborship is established and GR capability is exchanged,
+    transition restarting router to disabled state and vice versa.
+14. Verify that restarting nodes reset "F" bit while sending
+    the BGP open messages after it's restarts, when BGP GR is **NOT** enabled.
+15. Verify that only GR helper routers keep the stale
+    route entries, not any GR disabled router.
+16. Transition from Global Restarting to Disable and then Global
+    Disable to Restarting.
+17. Transition from Global Helper to Disable and then Global
+    Disable to Helper.
+18. Transition from Global Restart to Helper and then Global
+    Helper to Restart, Global Mode : GR Restarting
+    PerPeer Mode :  GR Helper
+    GR Mode effective : GR Helper
+19. Transition from Peer-level helper to Global Restarting,
+    Global Mode : GR Restarting
+    PerPeer Mode :  GR Restarting
+    GR Mode effective : GR Restarting
+20. Transition from Peer-level restart to Global Restart
+    Global Mode : GR Restarting
+    PerPeer Mode :  GR Restarting
+    GR Mode effective : GR Restarting
+21. Transition from Peer-level disabled to Global Restart
+    Global Mode : GR Restarting
+    PerPeer Mode : GR Disabled
+    GR Mode effective : GR Disabled
+22. Peer-level inherit from Global Restarting
+    Global Mode : GR Restart
+    PerPeer Mode :  None
+    GR Mode effective : GR Restart
+23. Transition from Peer-level disable to Global inherit helper
+    Global Mode : None
+    PerPeer Mode :  GR Disable
+    GR Mode effective : GR Disable
+
+These tests have been broken up into 4 sub python scripts because
+the totality of this run was fairly significant.

+Following tests are covered to test BGP Graceful Restart functionality.
+Basic Common Test steps for all the test case below :
+- Create topology (setup module)
+  Creating 2 routers topology, r1, r2 in IBGP
+- Bring up topology
+- Verify for bgp to converge
+- Configure BGP Garceful Restart on both the routers.
+
+1. Transition from Peer-level helper to Global Restarting
+2. Transition from Peer-level helper to Global inherit helper
+3. Transition from Peer-level restarting to Global inherit helper
+4. Default GR functional mode is Helper.
+5. Verify that the restarting node sets "R" bit while sending the
+   BGP open messages after the node restart, only if GR is enabled.
+6. Verify if restarting node resets R bit in BGP open message
+   during normal BGP session flaps as well, even when GR restarting
+   mode is enabled. Here link flap happen due to interface UP/DOWN.
+7. Verify if restarting node resets R bit in BGP
+   open message during normal BGP session flaps when GR is disabled.
+8. Verify that restarting nodes set "F" bit while sending
+   the BGP open messages after it restarts, only when BGP GR is enabled.
+9. Verify that only GR helper routers keep the stale
+   route entries, not any GR disabled router.
+10. Verify that GR helper routers keeps all the routes received
+    from restarting node if both the routers are configured as
+    GR restarting node.
+11. Verify that GR helper routers delete all the routes
+    received from a node if both the routers are configured as GR
+    helper node.
+12. After BGP neighborship is established and GR capability is exchanged,
+    transition restarting router to disabled state and vice versa.
+13. After BGP neighborship is established and GR capability is exchanged,
+    transition restarting router to disabled state and vice versa.
+14. Verify that restarting nodes reset "F" bit while sending
+    the BGP open messages after it's restarts, when BGP GR is **NOT** enabled.
+15. Verify that only GR helper routers keep the stale
+    route entries, not any GR disabled router.
+16. Transition from Global Restarting to Disable and then Global
+    Disable to Restarting.
+17. Transition from Global Helper to Disable and then Global
+    Disable to Helper.
+18. Transition from Global Restart to Helper and then Global
+    Helper to Restart, Global Mode : GR Restarting
+    PerPeer Mode :  GR Helper
+    GR Mode effective : GR Helper
+19. Transition from Peer-level helper to Global Restarting,
+    Global Mode : GR Restarting
+    PerPeer Mode :  GR Restarting
+    GR Mode effective : GR Restarting
+20. Transition from Peer-level restart to Global Restart
+    Global Mode : GR Restarting
+    PerPeer Mode :  GR Restarting
+    GR Mode effective : GR Restarting
+21. Transition from Peer-level disabled to Global Restart
+    Global Mode : GR Restarting
+    PerPeer Mode : GR Disabled
+    GR Mode effective : GR Disabled
+22. Peer-level inherit from Global Restarting
+    Global Mode : GR Restart
+    PerPeer Mode :  None
+    GR Mode effective : GR Restart
+23. Transition from Peer-level disable to Global inherit helper
+    Global Mode : None
+    PerPeer Mode :  GR Disable
+    GR Mode effective : GR Disable
+
+These tests have been broken up into 4 sub python scripts because
+the totality of this run was fairly significant.

+Following tests are covered to test BGP Graceful Restart functionality.
+Basic Common Test steps for all the test case below :
+- Create topology (setup module)
+  Creating 7 routers topology
+- Bring up topology
+- Verify for bgp to converge
+- Configure BGP Graceful Restart on both the routers.
+
+TC_1_2:
+    Verify that EOR message is sent out only after initial convergence
+    Verify whether EOR message is received from all the peers after restart
+TC_3:
+    Verify the selection deferral timer functionality when EOR is not sent
+    by the helper router
+TC_11:
+    Verify that selection-deferral timer sets the maximum time to
+    avoid deadlock during which the best-path
+TC_10:
+    Test Objective : Test GR scenarios on helper router by enabling
+    Graceful Restart for multiple address families.
+TC_15:
+    Test Objective : Test GR scenarios by enabling Graceful Restart
+    for multiple address families..
+TC_16:
+    Test Objective : Verify BGP-GR feature when restarting node
+    is a transit router for it's iBGP peers.
+TC_18:
+    Test Objective : Verify that GR helper router deletes stale routes
+    received from restarting node, if GR capability is not present in
+TC_19:
+    Test Objective : Verify that GR routers keeps all the routes
+     received from restarting node if both the routers are
+TC_26:
+    Test Objective : Test GR scenarios on helper router by enabling
+    Graceful Restart for multiple address families.
+TC_28:
+    Test Objective : Verify if helper node goes down before restarting
+    node comes up online, helper node sets the R-bit to avoid dead-lock
+TC_29:
+    Test Objective : Change timers on the fly, and
+    verify if it takes immediate effect.
+TC_33:
+    Test Objective : Helper router receives same prefixes from two
+    different routers (GR-restarting and GR-disabled). Keeps the
+TC_34_1:
+    Test Objective : Restarting node doesn't preserve forwarding
+    state, helper router should not keep the stale entries.
+TC_34_2:
+    Test Objective : Restarting node doesn't preserve the forwarding
+    state verify the behaviour on helper node, if it still keeps the
+TC_32:
+    Test Objective : Restarting node is connected to multiple helper
+    nodes, one of them doesn't send EOR to restarting router. Verify
+TC_37:
+    Test Objective : Verify if helper node restarts before sending the
+    EOR message, restarting node doesn't wait until stale path timer
+TC_30:
+    Test Objective : Restarting node removes stale routes from Zebra
+    after receiving an EOR from helper router.

+Following tests are covered to test BGP Graceful Restart functionality.
+Basic Common Test steps for all the test case below :
+- Create topology (setup module)
+  Creating 7 routers topology
+- Bring up topology
+- Verify for bgp to converge
+- Configure BGP Graceful Restart on both the routers.
+
+TC_1_2:
+    Verify that EOR message is sent out only after initial convergence
+    Verify whether EOR message is received from all the peers after restart
+TC_3:
+    Verify the selection deferral timer functionality when EOR is not sent
+    by the helper router
+TC_11:
+    Verify that selection-deferral timer sets the maximum time to
+    avoid deadlock during which the best-path
+TC_10:
+    Test Objective : Test GR scenarios on helper router by enabling
+    Graceful Restart for multiple address families.
+TC_15:
+    Test Objective : Test GR scenarios by enabling Graceful Restart
+    for multiple address families..
+TC_16:
+    Test Objective : Verify BGP-GR feature when restarting node
+    is a transit router for it's iBGP peers.
+TC_18:
+    Test Objective : Verify that GR helper router deletes stale routes
+    received from restarting node, if GR capability is not present in
+TC_19:
+    Test Objective : Verify that GR routers keeps all the routes
+     received from restarting node if both the routers are
+TC_26:
+    Test Objective : Test GR scenarios on helper router by enabling
+    Graceful Restart for multiple address families.
+TC_28:
+    Test Objective : Verify if helper node goes down before restarting
+    node comes up online, helper node sets the R-bit to avoid dead-lock
+TC_29:
+    Test Objective : Change timers on the fly, and
+    verify if it takes immediate effect.
+TC_33:
+    Test Objective : Helper router receives same prefixes from two
+    different routers (GR-restarting and GR-disabled). Keeps the
+TC_34_1:
+    Test Objective : Restarting node doesn't preserve forwarding
+    state, helper router should not keep the stale entries.
+TC_34_2:
+    Test Objective : Restarting node doesn't preserve the forwarding
+    state verify the behaviour on helper node, if it still keeps the
+TC_32:
+    Test Objective : Restarting node is connected to multiple helper
+    nodes, one of them doesn't send EOR to restarting router. Verify
+TC_37:
+    Test Objective : Verify if helper node restarts before sending the
+    EOR message, restarting node doesn't wait until stale path timer
+TC_30:
+    Test Objective : Restarting node removes stale routes from Zebra
+    after receiving an EOR from helper router.

+Following tests are covered to test BGP Graceful Restart functionality.
+Basic Common Test steps for all the test case below :
+- Create topology (setup module)
+  Creating 7 routers topology
+- Bring up topology
+- Verify for bgp to converge
+- Configure BGP Graceful Restart on both the routers.
+
+TC_1_2:
+    Verify that EOR message is sent out only after initial convergence
+    Verify whether EOR message is received from all the peers after restart
+TC_3:
+    Verify the selection deferral timer functionality when EOR is not sent
+    by the helper router
+TC_11:
+    Verify that selection-deferral timer sets the maximum time to
+    avoid deadlock during which the best-path
+TC_10:
+    Test Objective : Test GR scenarios on helper router by enabling
+    Graceful Restart for multiple address families.
+TC_15:
+    Test Objective : Test GR scenarios by enabling Graceful Restart
+    for multiple address families..
+TC_16:
+    Test Objective : Verify BGP-GR feature when restarting node
+    is a transit router for it's iBGP peers.
+TC_18:
+    Test Objective : Verify that GR helper router deletes stale routes
+    received from restarting node, if GR capability is not present in
+TC_19:
+    Test Objective : Verify that GR routers keeps all the routes
+     received from restarting node if both the routers are
+TC_26:
+    Test Objective : Test GR scenarios on helper router by enabling
+    Graceful Restart for multiple address families.
+TC_28:
+    Test Objective : Verify if helper node goes down before restarting
+    node comes up online, helper node sets the R-bit to avoid dead-lock
+TC_29:
+    Test Objective : Change timers on the fly, and
+    verify if it takes immediate effect.
+TC_33:
+    Test Objective : Helper router receives same prefixes from two
+    different routers (GR-restarting and GR-disabled). Keeps the
+TC_34_1:
+    Test Objective : Restarting node doesn't preserve forwarding
+    state, helper router should not keep the stale entries.
+TC_34_2:
+    Test Objective : Restarting node doesn't preserve the forwarding
+    state verify the behaviour on helper node, if it still keeps the
+TC_32:
+    Test Objective : Restarting node is connected to multiple helper
+    nodes, one of them doesn't send EOR to restarting router. Verify
+TC_37:
+    Test Objective : Verify if helper node restarts before sending the
+    EOR message, restarting node doesn't wait until stale path timer
+TC_30:
+    Test Objective : Restarting node removes stale routes from Zebra
+    after receiving an EOR from helper router.

+Following tests are covered to test BGP Graceful Restart functionality.
+Basic Common Test steps for all the test case below :
+- Create topology (setup module)
+  Creating 7 routers topology
+- Bring up topology
+- Verify for bgp to converge
+- Configure BGP Graceful Restart on both the routers.
+
+TC_1_2:
+    Verify that EOR message is sent out only after initial convergence
+    Verify whether EOR message is received from all the peers after restart
+TC_3:
+    Verify the selection deferral timer functionality when EOR is not sent
+    by the helper router
+TC_11:
+    Verify that selection-deferral timer sets the maximum time to
+    avoid deadlock during which the best-path
+TC_10:
+    Test Objective : Test GR scenarios on helper router by enabling
+    Graceful Restart for multiple address families.
+TC_15:
+    Test Objective : Test GR scenarios by enabling Graceful Restart
+    for multiple address families..
+TC_16:
+    Test Objective : Verify BGP-GR feature when restarting node
+    is a transit router for it's iBGP peers.
+TC_18:
+    Test Objective : Verify that GR helper router deletes stale routes
+    received from restarting node, if GR capability is not present in
+TC_19:
+    Test Objective : Verify that GR routers keeps all the routes
+     received from restarting node if both the routers are
+TC_26:
+    Test Objective : Test GR scenarios on helper router by enabling
+    Graceful Restart for multiple address families.
+TC_28:
+    Test Objective : Verify if helper node goes down before restarting
+    node comes up online, helper node sets the R-bit to avoid dead-lock
+TC_29:
+    Test Objective : Change timers on the fly, and
+    verify if it takes immediate effect.
+TC_33:
+    Test Objective : Helper router receives same prefixes from two
+    different routers (GR-restarting and GR-disabled). Keeps the
+TC_34_1:
+    Test Objective : Restarting node doesn't preserve forwarding
+    state, helper router should not keep the stale entries.
+TC_34_2:
+    Test Objective : Restarting node doesn't preserve the forwarding
+    state verify the behaviour on helper node, if it still keeps the
+TC_32:
+    Test Objective : Restarting node is connected to multiple helper
+    nodes, one of them doesn't send EOR to restarting router. Verify
+TC_37:
+    Test Objective : Verify if helper node restarts before sending the
+    EOR message, restarting node doesn't wait until stale path timer
+TC_30:
+    Test Objective : Restarting node removes stale routes from Zebra
+    after receiving an EOR from helper router.

+Test the ability to initiate and stop BGP graceful shutdown.
+Test both the vrf-specific and global configuration and operation.
+
+r1
+|
+r2----r3
+| \
+|  \
+r4  r5
+
+
+r2 is UUT and peers with r1 and r3 in default bgp instance and
+with r4 and r5 in vrf vrf1.
+r1-r2 peering is iBGP and the other peerings are eBGP.
+
+Check r2 initial convergence in default table
+Define update-delay with max-delay in the default bgp instance on r2
+Shutdown peering on r1 toward r2 so that delay timers can be exercised
+Clear bgp neighbors on r2 and then check for the 'in progress' indicator
+Check that r2 only installs route learned from r4 after the max-delay timer expires
+Define update-delay with max-delay and estabish-wait and check json output showing set
+Clear neighbors on r2 and check that r3 installs route from r4 after establish-wait time
+Remove update-delay timer on r2 to verify that it goes back to normal behavior
+Clear neighbors on r2 and check that route install time on r2 does not delay
+Define global bgp update-delay with max-delay and establish-wait on r2
+Check that r2 default instance and vrf1 have the max-delay and establish set
+Clear neighbors on r2 and check route-install time is after the establish-wait timer
+
+Note that the keepalive/hold times were changed to 3/9 and the connect retry timer
+to 10 to improve the odds the convergence timing in this test case is useful in the
+event of packet loss.

+Following tests are covered to test large-community/community functionality:
+1.  Verify if large community attribute can be configured only in correct
+    canonical format.
+2.  Verify that the community attribute value, which we have advertised are
+    received in correct format and values, at the receiving end.
+3.  Verify BGP Large Community attribute"s transitive property attribute.
+4.  Verify that BGP Large Communities attribute are malformed, if the length of
+    the BGP Large Communities Attribute value, expressed in octets,
+    is not a non-zero multiple of 12.
+5.  Verify if overriding large community values works fine.
+6.  Verify that large community values" aggregation works fine.
+7.  Standard community also work fine in conjunction with large-community.
+8.  Matching prefixes based on attributes other than prefix list and make use
+    of set clause (IPV6).
+9.  Matching prefixes based on attributes other than prefix list and make use
+    of set clause (IPV4).
+10. Verify community and large-community list operations in route-map with all
+    clause (exact, all, any, regex) works.
+11. Verify that any value in BGP Large communities for boundary values.
+12. Clear BGP neighbor-ship and check if large community and community
+    attributes are getting re-populated.

+test_bgp_large_community_topo_1.py: Test BGP large community.
+
+Following tests are covered:
+1. Verify the standard large-community-lists can permit or deny
+   large community attribute only in the correct canonical format.
+2. Verify the expanded large-community-lists can permit or deny
+   large community attribute both in the correct canonical format
+   as well as REG_EX.
+3. Verify that we can modify a large-community-list is in use,
+   to add/remove attribute value and it takes immediate effect.
+4. Verify that large community attribute gets advertised when
+   route-map is applied to a neighbor and cleared when route-map
+   is removed.
+5. Verify that duplicate BGP Large Community values are NOT be transmitted.
+6. Verify if we want to remove all the large-community attributes from a
+   set of prefix we can set the value as NONE.
+7. Redistribute connected and static routes in BGP process with a route-map
+   appending/removing L-comm attributes.
+8. Verify if we want to remove specific large-community values from
+   a set of prefix we can make use of DELETE operation based on L-comm list.
+9. Verify that if community values are NOT be advertised to a specific
+   neighbour, we negate send-community command.
+   (Send-community all is enabled by default for all neighbors)
+10. Verify that large-community lists can not be configured without providing
+    specific L-community values(for match/delete operation in a route-map).
+11. Verify that Match_EXACT clause should pass only if all of the L-comm
+    values configured (horizontally) in the community list is present in
+    the prefix.  There must be no additional L-communities in the prefix.
+12. Verify that Match_ALL clause should pass only if ALL of the L-comm values
+    configured (horizontally) in the community list is present in the prefix.
+    There could be additional L-communities in the prefix that are not present
+    in the L-comm list.
+13. Verify that Match_ANY clause should pass only if at-least any one L-comm
+    value configured(vertically) in large-community list, is present in prefixes.
+14. Verify large-community lists operation in a route-map with match RegEx
+    statements.

+This topology is for validating one of the primary use cases for
+weighted ECMP (a.k.a. Unequal cost multipath) using BGP link-bandwidth:
+https://tools.ietf.org/html/draft-mohanty-bess-ebgp-dmz
+
+The topology consists of two PODs. Pod-1 consists of a spine switch
+and two leaf switches, with two servers attached to the first leaf and
+one to the second leaf. Pod-2 consists of one spine and one leaf, with
+one server connected to the leaf. The PODs are connected by a super-spine
+switch.
+
+Note that the use of the term "switch" above is in keeping with common
+data-center terminology. These devices are all regular routers; for
+this scenario, the servers are also routers as they have to announce
+anycast IP (VIP) addresses via BGP.

+Following tests are covered to test BGP Multi-VRF:
+
+FUNC_1:
+    Within each VRF, each address must be unambiguous on DUT.
+FUNC_2:
+    Different VRFs can have ambiguous/overlapping
+    addresses on DUT.
+FUNC_3:
+    Create static routes(IPv4+IPv6) associated to specific VRFs
+    and verify on DUT that same prefixes are present in corresponding
+    routing table.
+FUNC_4_&_5:
+    Each VRF should be mapped with a unique VLAN on DUT
+    for traffic segregation, when using a single physical interface.
+FUNC_6:
+    Advertise same set of prefixes from different VRFs
+    and verify on remote router that these prefixes are not
+    leaking to each other
+FUNC_7:
+    Redistribute Static routes and verify on remote routers
+    that routes are advertised within specific VRF instance, which
+    those static routes belong to.
+FUNC_8:
+    Test end to end traffic isolation based on VRF tables.
+FUNC_9:
+    Use static routes for inter-vrf communication
+    (route-leaking) on DUT.
+FUNC_10:
+    Verify intra-vrf and inter-vrf communication between
+    iBGP peers.
+FUNC_11:
+    Verify intra-vrf and inter-vrf communication
+    between eBGP peers.
+FUNC_12_a:
+    Configure route-maps within a VRF, to alter BGP attributes.
+    Verify that route-map doesn't affect any other VRF instances'
+    routing on DUT.
+FUNC_12_b:
+    Configure route-maps within a VRF, to alter BGP attributes.
+    Verify that route-map doesn't affect any other VRF instances'
+    routing on DUT.
+FUNC_12_c:
+    Configure route-maps within a VRF, to alter BGP attributes.
+    Verify that route-map doesn't affect any other VRF instances'
+    routing on DUT.
+FUNC_12_d:
+    Configure route-maps within a VRF, to alter BGP attributes.
+    Verify that route-map doesn't affect any other VRF instances'
+    routing on DUT.
+FUNC_12_e:
+    Configure route-maps within a VRF, to alter BGP attributes.
+    Verify that route-map doesn't affect any other VRF instances'
+    routing on DUT.
+FUNC_12_f:
+    Configure route-maps within a VRF, to alter BGP attributes.
+    Verify that route-map doesn't affect any other VRF instances'
+    routing on DUT.
+FUNC_13:
+    Configure a route-map on DUT to match traffic based
+    on a VRF interfaces.
+FUNC_14:
+    Test VRF-lite with Static+BGP originated routes.
+FUNC_15:
+    Configure prefix-lists on DUT and apply to BGP peers to
+    permit/deny prefixes.
+FUNC_16_1:
+    Configure a route-map on DUT to match traffic based various
+    match/set causes.
+FUNC_16_2:
+    Configure a route-map on DUT to match traffic based various
+    match/set causes.
+FUNC_16_3:
+    Configure a route-map on DUT to match traffic based various
+    match/set causes.

+Following tests are covered to test BGP Multi-VRF:
+
+CHAOS_1:
+    Do a shut and no shut on connecting interface of DUT,
+    to see if all vrf instances clear their respective BGP tables
+    during the interface down and restores when interface brought
+kCHAOS_3:
+    VRF leaking - next-hop interface is flapping.
+CHAOS_5:
+    VRF - VLANs - Routing Table ID - combination testcase
+    on DUT.
+CHAOS_9:
+    Verify that all vrf instances fall back
+    to backup path, if primary link goes down.
+CHAOS_6:
+    Restart BGPd daemon on DUT to check if all the
+    routes in respective vrfs are reinstalled..
+CHAOS_2:
+    Delete a VRF instance from DUT and check if the routes get
+    deleted from subsequent neighbour routers and appears again once VRF
+    is re-added.
+CHAOS_4:
+    Verify that VRF names are locally significant
+    to a router, and end to end connectivity depends on unique
+    virtual circuits (using VLANs or separate physical interfaces).
+CHAOS_8:
+    Restart all FRR services (reboot DUT) to check if all
+    the routes in respective vrfs are reinstalled.

+	interface r1-stub
+	 description Stub Network
+	 ip address 172.20.0.1/28
+	 no link-detect

+
+## Tests executed
+
+### Check if FRR is running
+
+Test is executed by running 
+
+	vtysh -c "show logging" | grep "Logging configuration for"
+	
+on router `R1`. This should return the logging information for all daemons registered
+to Zebra and the list of running daemons is compared to the daemons started for this
+test (`zebra` and `bgpd`)
+
+### Verify for BGP to converge
+
+BGP is expected to converge on each view within 60s total time. Convergence is verified by executing
+
+	vtysh -c "show ip bgp view 1 summary"
+	vtysh -c "show ip bgp view 2 summary"
+	vtysh -c "show ip bgp view 3 summary"
+
+and expecting 11 routes seen in the last column for each peer. (Each peer sends 11 routes)
+
+### Verifying BGP Routing Tables
+
+Routing table is verified by running 
+
+	vtysh -c "show ip bgp view 1"
+	vtysh -c "show ip bgp view 2"
+	vtysh -c "show ip bgp view 3"
+
+and comparing the result against the stored table in the r1/show_ip_bgp_view_NN.ref files
+(with NN 1, 2, 3) (A few header and trailer lines are cut/adjusted ahead of the compare to
+adjust for different output based on recent changes)

+test_bgp_peer-type_multipath-relax.py:
+
+Test the effects of the "bgp bestpath peer-type multipath-relax" command
+
+- enabling the command allows eBGP, iBGP, and confed routes to be multipath
+- the choice of best path is not affected
+- disabling the command removes iBGP/confed routes from multipath
+- enabling the command does not forgive eBGP routes of the requirement
+  (when enabled) that next hops resolve over connected routes
+- a mixed-type multipath next hop, when published to zebra, does not
+  require resolving next hops over connected routes
+- with the command enabled, an all-eBGP multipath next hop still requires
+  resolving next hops over connected routes when published to zebra
+
+Topology used by the test:
+
+                 eBGP  +------+  iBGP
+          peer1  ----  |  r1  |  ----  peer3
+                       |      |
+peer2  ----  r2  ----  |      |  ----  peer4
+       iBGP     confed +------+  eBGP
+
+r2 is present in this topology because ExaBGP does not currently support
+confederations so we use FRR to advertise the required AS_CONFED_SEQUENCE.
+
+Routes are advertised from different peers to form interesting multipaths.

+Following tests are covered to test bgp recursive route and ebgp
+multi-hop functionality:
+
+1.  Verify that BGP routes are installed in iBGP peer, only when there
+    is a recursive route for next-hop reachability.
+2.  Verify that any BGP prefix received with next hop as self-ip is
+    not installed in BGP RIB or FIB table.
+3.  Verify password authentication for eBGP and iBGP peers.
+4.  Verify that for a BGP prefix next-hop information doesn't change
+    when same prefix is received from another peer via recursive lookup.
+5.  Verify that BGP path attributes are present in CLI outputs and
+    JSON format, even if set to default.
+6.  Verifying the BGP peering between loopback and physical link's IP
+    of 2 peer routers.
+7.  Verify that BGP Active/Standby/Pre-emption/ECMP.

+BGP speakers conforming to this document (i.e., conformant BGP
+   speakers) MUST NOT locally generate BGP UPDATE messages containing
+   AS_SET or AS_CONFED_SET.  Conformant BGP speakers SHOULD NOT send BGP
+   UPDATE messages containing AS_SET or AS_CONFED_SET.  Upon receipt of

+"""Following tests are covered to test route-map functionality.
+TC_57:
+    Create route map to match prefix-list and permit inbound
+    and outbound prefixes and set criteria on match
+TC_52:
+    Test modify set/match clauses in a route-map to see
+    if it takes immediate effect.
+TC_61:
+    Delete the route maps.
+TC_50_1:
+    Test modify/remove prefix-lists referenced by a
+    route-map for match statement.
+TC_50_2:
+    Remove prefix-list referencec by route-map match cluase
+    and verifying it reflecting as intended
+TC_51:
+    Add and remove community-list referencec by route-map match cluase
+    and verifying it reflecting as intended
+TC_45:
+    Test multiple match statements as part of a route-map"s single
+    sequence number. (Logical OR-ed of multiple match statements)
+TC_44:
+    Test multiple match statements as part of a route-map"s single
+    sequence number. (Logical AND of multiple match statements)
+TC_41:
+    Test add/remove route-maps to specific neighbor and see if
+    it takes effect as intended
+TC_56:
+    Test clear BGP sessions and interface flaps to see if
+    route-map properties are intact.
+TC_46:
+    Verify if a blank sequence number can be create(without any
+    match/set clause) and check if it allows all the traffic/prefixes
+TC_48:
+    Create route map setting local preference and weight to eBGP peeer
+    and metric to ibgp peer and verifying it should not get advertised
+TC_43:
+    Test multiple set statements as part of a route-map"s
+    single sequence number.
+TC_54:
+    Verify route-maps continue clause functionality.
+TC_55:
+    Verify route-maps goto clause functionality.
+TC_53:
+    Verify route-maps call clause functionality.
+TC_58:
+    Create route map deny inbound and outbound prefixes on
+    match prefix list and set criteria on match
+TC_59:
+    Create route map to permit inbound prefixes with filter
+    match tag and set criteria
+TC_60

+Test the ability to define update-delay to delay bestpath, rib install

+
+
+r2 is UUT and peers with r1, r3, and r4 in default bgp instance.
+r2 peers with r5 in vrf vrf1.
+
+Check r2 initial convergence in default table
+Define update-delay with max-delay in the default bgp instance on r2
+Shutdown peering on r1 toward r2 so that delay timers can be exercised
+Clear bgp neighbors on r2 and then check for the 'in progress' indicator
+Check that r2 only installs route learned from r4 after the max-delay timer expires
+Define update-delay with max-delay and estabish-wait and check json output showing set
+Clear neighbors on r2 and check that r3 installs route from r4 after establish-wait time
+Remove update-delay timer on r2 to verify that it goes back to normal behavior
+Clear neighbors on r2 and check that route install time on r2 does not delay
+Define global bgp update-delay with max-delay and establish-wait on r2
+Check that r2 default instance and vrf1 have the max-delay and establish set
+Clear neighbors on r2 and check route-install time is after the establish-wait timer
+
+Note that the keepalive/hold times were changed to 3/9 and the connect retry timer
+to 10 to improve the odds the convergence timing in this test case is useful in the
+event of packet loss.

+Following tests are covered to test BGP Multi-VRF Dynamic Route Leaking:
+
+1. Verify that dynamically imported routes are further advertised
+    to iBGP peers(peer in cluster).
+2. Verify matching a prefix based on community attribute and
+    importing it by stripping off this value
+3. Verify the route-map operation along with dynamic import command.
+4. Verifying the JSON outputs for all supported commands

+Following tests are covered to test BGP Multi-VRF Dynamic Route Leaking:
+1. Verify that with multiple tenant VRFs, dynamically imported routes are
+    further advertised to eBGP peers.
+2. Verify the route-map operations along with dynamic import command
+3. Verify that deleting static routes from originating VRF also deletes
+    routes from other VRFs and peers.
+4. Verify that deleting and adding "import" command multiple times shows
+    consistent results.

+2. Verify that dynamic import works fine between two different Tenant VRFs.
+    When next-hop IPs are same across all VRFs.
+    When next-hop IPs are different across all VRFs.
+3. Verify that with multiple tenant VRFs, dynamic import works fine between
+    Tenant VRFs to default VRF.
+    When next-hop IPs and prefixes are same across all VRFs.
+    When next-hop IPs and prefixes are different across all VRFs.

+Test the timing of config operations.
+
+The initial add of 10k routes is used as a baseline for timing and all future
+operations are expected to complete in under 2 times that baseline. This is a
+lot of slop; however, the pre-batching code some of these operations (e.g.,
+adding the same set of 10k routes) would take 100 times longer, so the intention
+is to catch those types of regressions.

+# Topotests in Docker
+
+## Quickstart
+
+If you have Docker installed, you can run the topotests in Docker.
+The easiest way to do this, is to use the make targets from this
+repository.
+
+Your current user needs to have access to the Docker daemon. Alternatively
+you can run these commands as root.
+
+```console
+make topotests
+```
+
+This command will pull the most recent topotests image from dockerhub, compile FRR inside
+of it, and run the topotests.
+
+## Advanced Usage
+
+Internally, the topotests make target uses a shell script to pull the image and spawn the docker
+container.
+
+There are several environment variables which can be used to modify the behavior
+of the script, these can be listed by calling it with `-h`:
+
+```console
+./tests/topotests/docker/frr-topotests.sh -h
+```
+
+For example, a volume is used to cache build artifacts between multiple runs
+of the image. If you need to force a complete recompile, you can set `TOPOTEST_CLEAN`:
+
+```console
+TOPOTEST_CLEAN=1 ./tests/topotests/docker/frr-topotests.sh
+```
+
+By default, `frr-topotests.sh` will build frr and run pytest. If you append
+arguments and the first one starts with `/` or `./`, they will replace the call to
+pytest. If the appended arguments do not match this patttern, they will be provided to
+pytest as arguments.
+
+So, to run a specific test with more verbose logging:
+
+```console
+./tests/topotests/docker/frr-topotests.sh -vv -s all-protocol-startup/test_all_protocol_startup.py
+```
+
+And to compile FRR but drop into a shell instead of running pytest:
+
+```console
+./tests/topotests/docker/frr-topotests.sh /bin/bash
+```
+
+## Development
+
+The docker image just includes all the components to run the topotests, but not the topotests
+themselves. So if you just want to write tests and don't want to make changes to the environment
+provided by the docker image. You don't need to build your own docker image if you do not want to.
+
+When developing new tests, there is one caveat though: The startup script of the container will
+run a `git-clean` on its copy of the FRR tree to avoid any pollution of the container with build
+artefacts from the host. This will also result in your newly written tests being unavailable in the
+container unless at least added to the index with `git-add`.
+
+If you do want to test changes to the docker image, you can locally build the image and run the tests
+without pulling from the registry using the following commands:
+
+```console
+make topotests-build
+TOPOTEST_PULL=0 make topotests
+```

+Welcome to the topotests container.
+
+Here are some useful tips:
+* After changing the FRR/Topotests sources, you may rebuild them
+  using the command `compile_frr.sh`. The build command has the
+  following environment variables:
+  - TOPOTEST_CLEAN: whether we should distclean or not (disabled by default)
+  - TOPOTEST_VERBOSE: show build messages (enabled by default)
+  - TOPOTEST_DOC: whether we should build docs or not (disabled by default)
+  - TOPOTEST_SANITIZER: whether we should use the address sanitizer (enabled by default)
+
+  Usage example: env TOPOTEST_CLEAN=1 compile_frr.sh
+
+* The topotests log directory can be found on your host machine on
+  `/tmp/topotests_logs`.

+
+1. RD verification (manual/auto).
+2. RT verification(manual)
+3. In an active/standby EVPN implementation, if active DCG goes down,
+        secondary takes over.
+4. EVPN routes are advertised/withdrawn, based on VNFs
+        advertising/withdrawing IP prefixes.
+5. Route-map operations for EVPN address family.
+6. BGP attributes for EVPN address-family.

+Topogen (Topology Generator) is an abstraction around Topotest and Mininet to
+help reduce boilerplate code and provide a stable interface to build topology
+tests on.
+
+Basic usage instructions:
+
+* Define a Topology class with a build method using mininet.topo.Topo.
+  See examples/test_template.py.
+* Use Topogen inside the build() method with get_topogen.
+  e.g. get_topogen(self).
+* Start up your topology with: Topogen(YourTopology)
+* Initialize the Mininet with your topology with: tgen.start_topology()
+* Configure your routers/hosts and start them
+* Run your tests / mininet cli.
+* After running stop Mininet with: tgen.stop_topology()

+Following tests are covered to test PIM BSM processing basic functionality:
+
+Test steps
+- Create topology (setup module)
+- Bring up topology
+
+Tests covered in this suite
+1. Verify FRR router select higher IP BSR , when 2 BSR present in the network
+2. Verify BSR and RP updated correctly after configuring as black hole address
+3.1 Verify when new router added to the topology, FRR node will send
+    unicast BSM to new router
+3.2 Verify if  no forwarding bit is set , FRR is not forwarding the
+    BSM to other PIM nbrs
+3.3 Verify multicast BSM is sent to new router when unicast BSM is disabled
+4.1 Verify BSM arrived on non bsm capable interface is dropped and
+    not processed
+4.2 Verify group to RP info updated correctly in FRR node, after shut and
+    no-shut of BSM enable interfaces
+5. Verify static RP is preferred over BSR
+6.1 Verify adding/deleting the group to rp mapping and RP priority
+    multiple times
+6.2 Verify RP and (*,G) detail after PIM process restart on FRR node
+7.1 Verify BSM timeout on FRR1
+7.2 Verify RP state in FRR1 after Bootstrap timer expiry
+8.1 Verify upstream interfaces(IIF) and join state are updated properly
+    after BSM received for FRR
+8.2 Verify IIF and OIL in "show ip pim state" updated properly after
+    BSM received

+Following tests are covered to test PIM BSM processing basic functionality:
+
+Test steps
+- Create topology (setup module)
+- Bring up topology
+
+Tests covered in this suite
+1. Verify (*,G) mroute detail on FRR router after BSM rp installed
+2. Verify group to RP updated correctly on FRR router, when BSR advertising
+    the overlapping group address
+3. Verify group to RP info is updated correctly, when BSR advertising the
+    same RP with different priority
+4. Verify group to RP mapping in FRR node when 2 BSR are present in the network
+    and both are having same BSR priority
+5. Verify RP is selected based on hash function, when BSR advertising the group
+    to RP mapping with same priority
+6. Verify fragmentation of bootstrap message
+7. Verify when candidate RP advertised with 32 mask length
+    and contain all the contacts

+3. TC_4: Verify removing the RP should not impact the multicast
+   data traffic
+4. TC_5: Verify (*,G) and (S,G) entry populated again after clear the
+   PIM nbr and mroute from FRR node
+5. TC_9: Verify (s,g) timeout from FHR and RP when same receive
+   exist in LHR , FHR and RP
+6. TC_19: Verify mroute detail when same receiver joining 5
+    different sources
+7. TC_16: Verify (*,G) and (S,G) populated correctly
+    when FRR is the transit router
+8. TC_23: Verify (S,G) should not create if RP is not reachable
+9. TC_24: Verify modification of IGMP query timer should get update
+    accordingly
+10. TC_25: Verify modification of IGMP max query response timer
+    should get update accordingly

+Test steps
+- Create topology (setup module)
+- Bring up topology
+
+Following tests are covered:
+1. TC_17: Verify (*,G) and (S,G) present and multicast traffic resume,
+    after restart of PIMd daemon
+2. TC_18: Verify (*,G) and (S,G) present and multicast traffic resume after
+    FRR service stop and start

+test_ospf6_ecmp_inter_area.py: Test OSPFv3 ECMP inter-area nexthop update
+
+Check proper removal of ECMP nexthops after a path used by one nexthop
+disappears. We remove a path by bringing down a link required by that
+path which is not adjacent to the router being checked. This is important
+because when bringing down adjacent links, the kernel might remove the
+nexthops itself without ospf6d having to do anything.
+
+Useful as a regression test for #9720.
+
+Topology:
+             .
+      Area 0 . Area 1
+             .
+   -- R2 --  . ---- R6
+  /        \ ./
+R1 -- R3 -- R5 ---- R7  Area 1
+  \        /  \\ ..............
+   -- R4 --    \--- R8  Area 0
+                \
+                 -- R9
+
+We check routes on R1, primarily those towards R6/7/8/9. Those to R6/7 are
+inter-area routes with R5 being ABR, those to R8/9 are intra-area routes
+and are used for reference. R6/R8 announce external routes, R7/R9 announce
+internal routes.
+
+With all links up, we expect 3 ECMP paths and 3 nexthops on R1 towards each
+of R6/7/8/9. Then we bring down the R2-R5 link, causing only 2 remaining
+paths and 2 nexthops on R1. The test is successful if the number of nexthops
+for the routes on R1 is as expected.

+### Check if FRR is running
+
+Test is executed by running 
+
+	vtysh -c "show logging" | grep "Logging configuration for"
+	
+on each FRR router. This should return the logging information for all daemons registered
+to Zebra and the list of running daemons is compared to the daemons started for this test (`zebra` and `ospf6d`)
+
+### Verify for OSPFv3 to converge
+
+OSPFv3 is expected to converge on each view within 60s total time. Convergence is verified by executing (on each node)
+
+	vtysh -c "show ipv6 ospf neigh"
+
+and checking for "Full" neighbor status in the output. An additional 15 seconds after the full converge is waited for routes to populate before the following routing table checks are executed
+
+### Verifying OSPFv3 Routing Tables
+
+Routing table is verified by running 
+
+	vtysh -c "show ipv6 route"
+
+on each node and comparing the result to the stored example config (see `show_ipv6_route.ref` in r1 / r2 / r3 / r4 directories). Link-Local addresses are masked out before the compare.
+
+### Verifying Linux Kernel Routing Table
+
+Linux Kernel IPv6 Routing table is verified on each FRR node with
+
+	ip -6 route
+
+Tables are compared with reference routing table (see `ip_6_address.ref` in r1 / r2 / r3 / r4 directories). Link-Local addresses are translated after getting collected on each node with interface name to make them consistent

+## Tests executed
+
+### Check if FRR is running
+
+Test is executed by running 
+
+	vtysh -c "show logging" | grep "Logging configuration for"
+	
+on each FRR router. This should return the logging information for all daemons registered
+to Zebra and the list of running daemons is compared to the daemons started for this test (`zebra` and `ospf6d`)
+
+### Verify for OSPFv3 to converge
+
+OSPFv3 is expected to converge on each view within 60s total time. Convergence is verified by executing (on each node)
+
+	vtysh -c "show ipv6 ospf vrf r1-cust1 neigh"
+
+and checking for "Full" neighbor status in the output. An additional 15 seconds after the full converge is waited for routes to populate before the following routing table checks are executed
+
+### Verifying OSPFv3 Routing Tables
+
+Routing table is verified by running 
+
+	vtysh -c "show ipv6 route vrf r1-cust1"
+
+on each node and comparing the result to the stored example config (see `show_ipv6_route.ref` in r1 / r2 / r3 / r4 directories). Link-Local addresses are masked out before the compare.
+
+### Verifying Linux Kernel Routing Table
+
+Linux Kernel IPv6 Routing table is verified on each FRR node with
+
+	ip -6 route vrf r1-cust1
+
+Tables are compared with reference routing table (see `ip_6_address.ref` in r1 / r2 / r3 / r4 directories). Link-Local addresses are translated after getting collected on each node with interface name to make them consistent

+test_pim_acl.py: Test PIM with RP selection using ACLs
+"""
+
+# Test PIM RP selection with ACLs
+#
+# Testing RP selection with ACLs. R1 uses multiple ACLs
+# to select desired RPs (R11 to R15)
+#
+# Test steps:
+# - setup_module()
+#     Create topology. Hosts are only using zebra/staticd,
+#     no PIM, no OSPF (using IGMPv2 for multicast)
+# - test_ospf_convergence()
+#     Wait for OSPF convergence in each VRF. OSPF is run on
+#     R1 and R11 - R15.
+# - test_pim_convergence()
+#     Wait for PIM convergence on all routers. PIM is run on
+#     R1 and R11 - R15.
+# - test_mcast_acl_1():
+#     Test 1st ACL entry 239.100.0.0/28 with 239.100.0.1 which
+#     should use R11 as RP
+#     Stop multicast after verification
+# - test_mcast_acl_2():
+#     Test 2nd ACL entry 239.100.0.17/32 with 239.100.0.17 which
+#     should use R12 as RP
+#     Stop multicast after verification
+# - test_mcast_acl_3():
+#     Test 3rd ACL entry 239.100.0.32/27 with 239.100.0.32 which
+#     should use R13 as RP
+#     Stop multicast after verification
+# - test_mcast_acl_4():
+#     Test 4th ACL entry 239.100.0.128/25 with 239.100.0.255 which
+#     should use R14 as RP
+#     Stop multicast after verification
+# - test_mcast_acl_5():
+#     Test 5th ACL entry 239.100.0.96/28 with 239.100.0.97 which
+#     should use R14 as RP
+#     Stop multicast after verification
+# - test_mcast_acl_6():
+#     Test 6th ACL entry 239.100.0.64/28 with 239.100.0.70 which
+#     should use R15 as RP
+#     Stop multicast after verification

+# Tests PIM with VRF
+#
+# R1 is split into 2 VRF: Blue and Red, the others are normal
+# routers and Hosts
+# There are 2 similar topologies with overlapping IPs in each
+# section.
+#
+# Test steps:
+# - setup_module()
+#     Create topology. Hosts are only using zebra/staticd,
+#     no PIM, no OSPF (using IGMPv2 for multicast)
+# - test_ospf_convergence()
+#     Wait for OSPF convergence in each VRF. OSPF is run on
+#     R1, R11 and R12.
+# - test_pim_convergence()
+#     Wait for PIM convergence in each VRF. PIM is run on
+#     R1, R11 and R12. R11 is the RP for vrf blue, R12 is RP
+#     for vrf red.
+# - test_vrf_pimreg_interfaces()
+#     Adding PIM RP in VRF information and verify pimreg
+#     interfaces in VRF blue and red
+# - test_mcast_vrf_blue()
+#     Start multicast stream for group 239.100.0.1 from Host
+#     H2 and join from Host H1 on vrf blue
+#     Verify PIM JOIN status on R1 and R11
+#     Stop multicast after verification
+# - test_mcast_vrf_red()
+#     Start multicast stream for group 239.100.0.1 from Host
+#     H4 and join from Host H3 on vrf blue
+#     Verify PIM JOIN status on R1 and R12
+#     Stop multicast after verification
+# - teardown_module(module)
+#     shutdown topology
