## 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

## 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)
