[c-nsp] Sup1a MSFC2 Policy Based Routing

Hey all,
I am having some problems getting policy based routing (using a
access-list to identify source) working on a 6500 with a Sup1a / MSFC2
card. Background of the setup is the following:
1. Have 4 BGP peers using equal weight in and out for routing choices.
2. 6500 is running in Native IOS with version
c6sup12-ps-mz.121-26.E3.bin and c6msfc2-boot-mz.121-26.E3.bin.
I am trying to use source based routing to control one of my subnets
outbound traffic to use a lower cost BGP peer over the other 3. The
source address in this case we will use 1.1.1.0/28 and is directly
connecting to f 3/10. The BGP peer router I want the traffic to go out
is 4.4.4.10 and is directly connected to g 1/1. So I setup the following
route-map and identify the source network via an access-list with the
following configuration.
access-list 180 permit ip 1.1.1.0 0.0.0.16 any
route-map peer-out permit 10
match ip address 180
set ip next-hop 4.4.4.10
This is where I get a bit lost. I assigned this route map to the
interface in which the 1.1.1.0 network was attached with this.
interface f 3/10
ip policy route-map peer-out
I don't see the policy routing matches increasing when I do a show
route-map peer-out. On top of that, if I traceroute from any server in
the 1.1.1.0/28 network to the outside world, it still uses the BGP
preferred route from the route table. Is there something I am doing
wrong here to override the outbound traffic for this subnet to go over a
desired BGP peer?
Any help would be greatly appreciated.
Regards,
jason
