Policy route map with BGP

[darnoctai]

Hi,

I was wondering how possible it would be to do policy based route map a resilient connection, if at all possible. For example, in the following config...

interface Ethernet3/0
ip address 172.16.79.3 255.255.255.0
no ip directed-broadcast
ip policy route-map net-10
!

access-list 111 permit ip 10.0.0.0 0.255.255.255 any
!
route-map net-10 permit 10
match ip address 111
set interface Ethernet0/1
!
route-map net-10 permit 20
!

.....the policy map is attached to interface 3/0 such that any traffic with source ip in the 10.0.0.0/8 range is routed through interface 0/1. Now, provided that the ethernet link was down, how possible would it be to automatically switch this routing to a seperate link on a different interface? BGP perhaps?

..tnx!

Are you actually looking for tracking in PBR?

Check the IOS requirement and see if you already got this.

Thanks for your reply!

This would be ideal, but it looks as if it requires CDP. Unfortunately my remote peers are two upstream providers and I will not be able to operate using CDP. Are there any other link/IP tracking alternatives which simply use ICMP?

Try this then:
