Hello, I have a 3600 series router with an ethernet interface and two serial interfaces. Each serial interface connects to a separate ISP. The ISPs are sending us full routes via BGP, but for whatever reason there are issues balancing the load. We would like to force traffic leaving the router destined to a certain network out of a specific interface. By default it is passing the traffic to neighbor AS XXX (AS associated with ISP A). I have tried a couple different routes to chage the behavior. One, I tried a static route to the AS XXXX of ISP B. It goes there but immediately after the first hop it uses AS paths of ISP A. Then I just tried a static route with the interface name of serial0/1 (ISP B serial). Still it takes the default AS path of ISP A. Aside from routes being cached are there other configuration detail to be aware of when trying this?
Re: Forcing a route through an alternate interface
Ok. Here is my config related to policy routing. The interface I want the traffic to leave is Serial0/0. I replaced the IP's with X's, they are valid IP addresses / networks. I do not fully understand what I read, but think I have a basic idea. Its not working though. Still takes AS of ISP A.
ip address X.X.X.X 255.255.255.252
encapsulation frame-relay IETF
no ip mroute-cache
ip policy route-map net-XX.XX.XXX
service-module t1 timeslots 1-24
service-module t1 remote-alarm-enable
frame-relay map ip X.X.X.X 16 broadcast IETF
frame-relay lmi-type ansi
access-list 111 permit ip X.0.0.0 0.255.255.255 any
