Hi All,

I know I need to change the rpf neighbor so that I use s0/2/0 interface on R2 instead of the gi0/1 . I struggle to change the RPF neighbor with the route-map.


route-map CHANGENEXT permit 10
 set ip next-hop 192.0.52.2
!
or with

route-map CHANGENEXT permit 10
 set ip next-hop 192.0.52.5
!
I have applied this route-map to the neighbor in multicast address-family


router bgp 52
 bgp router-id 192.0.0.2
 bgp log-neighbor-changes
 bgp confederation identifier 25
 neighbor 192.0.0.5 remote-as 52
 neighbor 192.0.0.5 update-source Loopback0
 neighbor 192.0.12.1 remote-as 11314
 neighbor 192.0.212.21 remote-as 11314
 neighbor 192.0.245.4 remote-as 47
 !

I have cleared the neighbor sessions but I cannot see the change in rpf.

R2(config-router-af)#do show bgp ipv4 multicast summary

What am I missing here?
