Hello,
I have two routers working as main and backup via HSRP. Both of them are advertising the subnet 172.10.10.0/24, the question is I need that the packets with destiny 172.10.10.64/26 subnet, go through the backup router. I applied a route-map with a prefix-list in backup router that include the 172.10.10.64/26 subnet with a better metric. However the packets which are sent to that subnet go through main router. This is the configuration:
- Backup Router (standby status)
router bgp 1000
no synchronization
bgp log-neighbor-changes
network 172.10.10.0
redistribute connected
redistribute static
neighbor iBGP peer-group
neighbor iBGP remote-as 1000
neighbor iBGP route-map iBGP-OUT out
neighbor x.x.x.x remote-as 500
neighbor x.x.x.x description BGP
neighbor x.x.x.x timers 10 30
neighbor x.x.x.x next-hop-self
neighbor x.x.x.x send-community
neighbor x.x.x.x route-map INPUT_NET in
neighbor x.x.x.x route-map USER_NET out
neighbor y.y.y.y peer-group iBGP
neighbor z.z.z.z peer-group iBGP
no auto-summary

What can i do?
Note: The objetive is all traffic with source or destination 172.10.10.64/26 subnet go through backup router. If backup router fails, the traffic tothat subnet must go through the main router.
Thank you and sorry for my english
