Hi,
Im about to implement a Policy Based Routing in a complex environment.
I'm a little bit frustrated with the monitoring possibilites, which can be applied on a route-map for policy based Routing.
I've attached a picture, to explain my problem a little bit easier.
I'd like to route Traffic from Host A 172.16.0.5 to Host B 192.168.50.5 via Policy Based Routing. It's not really a problem to implement this, but i would like to add more availability monitoring options.
I've defined one Route Map on A_Router1 and A_Router2:
route-map PBR
match ip address PBR
set ip next-hop verify-availability 10 10.0.0.3 track 130 (includes icmp check to B_ISP RTR1 and B_ISP RTR2)
set ip next-hop verify-availability 20 10.0.0.4 track 130 (includes icmp check to B_ISP RTR1 and B_ISP RTR2)
PBR ACL
permit ip host 172.16.0.5 host 192.168.50.5
The setup works fine, but now to my problem. I need a possibility to verify the availability of my next-hop in combination of the track 130.
Otherwise the Router will use 10.0.0.3 still as next-hop, although it's not reachable anymore. Because the track 130 is still up (via 10.0.0.4).
This means i need an OR correlation. If the next-hop is not available or if the track 130 is down, than check the next sequence number and then ignore the route-map.
I also tried to achieve this with set ip next-hop recursive. But in my scenario it dosn't work, because the fallback would be my default route.
It's only a port of the whole setup. To explain the whole setup it would take a lot of time. I hope it's understandable what i triy to achieve.
Do you have an idea to solve my problem? Thank you very much.
