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.
¡Resuelto! Ir a solución.

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.
