+## FRR Configuration
+
+Full config as used is in r1 subdirectory
+
+Simplified `R1` config:
+
+	hostname r1
+	!
+	interface r1-stub
+	 description Stub Network
+	 ip address 172.20.0.1/28
+	 no link-detect
+	!
+	interface r1-eth0
+	 description to PE router - vlan1
+	 ip address 172.16.1.254/24
+	 no link-detect
+	!
+	router bgp 100 view 1
+	 bgp router-id 172.30.1.1
+	 network 172.20.0.0/28 route-map local1
+	 timers bgp 60 180
+	 neighbor 172.16.1.1 remote-as 65001
+	 neighbor 172.16.1.2 remote-as 65002
+	 neighbor 172.16.1.5 remote-as 65005
+	!
+	router bgp 100 view 2
+	 bgp router-id 172.30.1.1
+	 network 172.20.0.0/28 route-map local2
+	 timers bgp 60 180
+	 neighbor 172.16.1.3 remote-as 65003
+	 neighbor 172.16.1.4 remote-as 65004
+	!
+	router bgp 100 view 3
+	 bgp router-id 172.30.1.1
+	 network 172.20.0.0/28
+	 timers bgp 60 180
+	 neighbor 172.16.1.6 remote-as 65006
+	 neighbor 172.16.1.7 remote-as 65007
+	 neighbor 172.16.1.8 remote-as 65008
+	!
+	route-map local1 permit 10
+	 set community 100:9999 additive
+	 set metric 0
+	!
+	route-map local2 permit 10
+	 set as-path prepend 100 100 100 100 100
+	 set community 100:1 additive
+	 set metric 9999

+
+## 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)
