I'm trying to speed up BGP failover when we lose our primary ISP connection (either physical or BGP Peer). I came up with this configuration to match the diagram below. Will this work or is there a better way?
NOTE - ISP #1 BGP Peer 1.1.1.1
NOTE - Router #2 BGP Peer 2.2.2.2
NOTE - Router #1 Internet Interface - TE2/2
Router #1 configuration:
ip sla 1
type echo protocol ipicmpecho 1.1.1.1
timeout 1000
frequency 3
ip sla schedule 1 life forever start-time now
track 1 ip sla 1 reachability
ip route 0.0.0.0 0.0.0.0 1.1.1.1 te2/2 1.1.1.1 track 1
ip access –list 101 permit icmp any host 1.1.1.1 echo
ip local policy route-map default-route-policy
route-map default-route-policy permit 1
match ip address 101
set ip next-hop 1.1.1.1
set interface null 0
ip route 0.0.0.0 0.0.0.0 1.1.1.1 track 1
ip route 0.0.0.0 0.0.0.0 2.2.2.2 200
router bgp 100
bgp timers 15 45
bgp log-neighbor-changes
neighbor IBGP peer-group
neighbor IBGP remote-as 100
neighbor IBGP update-source Loopback0
neighbor 2.2.2.2 peer-group IBGP neighbor 2.2.2.2 description iBGP peer with Router 2
neighbor 2.2.2.2 default-originate route-map default-route-policy
neighbor 1.1.1.1 remote-as 1
neighbor 1.1.1.1 description BGP peer with ISP#1
neighbor 1.1.1.1 update-source TenGigabitEthernet2/2
neighbor 1.1.1.1 fall-over route-map default-route-policy
IN BOTH Router 1 and 2
