policy-based routing don´t work

[Gewy]

Hi team,

I would like to share a question I have and get your comments on it.
I am currently working with route-maps and next hops on C881 and C887 devices, however I only have a problem with two of them.

My devices work fine with these commands:
route-map FILTER
permit 10 match ip address 101
set ip next-hop 172.16.244.254

But they don't work well with these commands:
route-map FILTER
permit 10 match ip address 101
set ip next-hop 172.16.243.254 172.16.244.254
set ip next-hop verify-availability

Does anyone know what could be causing it?
I remain attentive.

set ip next-hop verify-availability 172.16.244.254

The solution to my problem was to enable CDP general and on the tunnel interfaces. Because the PBR uses the CDP to be able to validate if the next hop I am pointing to is active:

route-map FILTER
set ip next-hop 172.16.243.254 172.16.244.254
set ip next-hop verify-availability

Alternatively I also made use of IP SLA Track, which basically does what cdp does; it validates that the next hop is active:

route-map FILTER
set ip next-hop verify-availability 172.16.244.254 10 track 11
set ip next-hop verify-availability 172.16.243.254 20 track 10

I hope you find it useful.
Best regards.
