So I have been attempting to use IOS-XR ABF (Access List Based Forwarding) to implement a "catch-all" next-hop of a destination within the same LAN (back out the same interface the packet arrived on). Cisco documentation indicates this would fall under the "for-us" rule and not work by default. However, I can see access list matches against this type of config. It appears the router is doing some of redirect because I do not see the packets arriving on the device of the next-hop that is configured.
I recently stumbled across ePBR (enhanced Policy Based Routing) which I thought PBR did not exist in ASR9000 routers (replaced by ABF). The configuration is pretty straight forwarding using class maps and a "redirect nexthop" under the policy-map class action. The policy-map is configured as a PBR with the class as a type "traffic". The policy-map is then applied in the input direction under the interface/sub-interface. Has anyone used ePBR and would it solve the problem of the ABF issue with attempting to same interface nexthop route? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
