Policy based routing

Unanswered Question

I am trying apply policy based routing on an MPLS WAN at the hub site to force all incoming traffic to go via the firewall rather than back out onto the WAN. I tried to create a route map with a match statement pointing to an AS-Path ACL but it doesn't work. The reason I wish to do this is because the remote sites run BGP and I can identify sites by AS number rather than IP address. I suspect it doesn't work because BGP is not using this ACL rather it is IP routing but has anyone ever tried this and got it working. Any help would be appreciated

regards

Ian

Hi,


I don't believe that this can be achieved as the packet that will be PBRed doesn't carry any AS info.

Hi Mohammed

thanks for the quick response. I thought that would be the case but wanted confirmation. I have one questions though that puzzles me, when I test this with the policy map applied all routing is PBRed where as I would have expected it to be destination based if it failed the match sequence
