route-maps/policy routing on 6506

Unanswered Question
Apr 12th, 2007

I am trying to use route maps to change the next hop address for traffic matching a certain criteria and apply the ip policy to a vlan interface rather than a physical interface. The network consists of 6506's with sup2's running native ios. Unfortunately I have been unsuccessful so far! All traffic routes through vlan 476 and on to a main production router, address 10.192.192.100. I want to make certain traffic route to another data migration router, 10.192.192.101.

Even though eigrp and redistributed statics are used I cannot add more routes as I need the granularity of making certain traffic route to the data migration router, keeping it from going across the main production WAN link whilst keeping other traffic going to the same destination using the production router.

Here is the basic config I am using.

route-map iplc-traffic permit 10

match ip address iplc

set ip next-hop 10.192.192.101

ip extended access-list iplc permit ip host 172.16.2.200 host 10.70.125.3

int vlan 476

ip address 10.192.192.1 255.255.255.0

ip policy route-map iplc-traffic

int vlan 2

ip add 172.16.0.0 255.255.0.0

router eigrp 1

network 172.16.0.0

network 10.192.192.0

ip route 10.64.0.0 255.255.0.0 10.192.192.100

If I look at the route map it shows no traffic has been policy routed and looking at the access-list shows no packets hitting it.

If anyone can help it would be much appreciated

Many thanks.

Paul.

I have this problem too.

Paul,

You need to apply the policy routing on vlan2 int. Policy routing works on the inbound direction only.

This should do it...

int vlan 2

ip policy route-map iplc-traffic

Thanks Sundar, now works a treat!! I guess my understanding of how access-lists work on 6500's was wrong.
