Load Balancing via Two separate routes on outside of Firewall

[jclemmons]

I have two Cisco routers on LAN interface with outside segment of PIX525, both terminating T1 connections to same client site. Want to be able to load balance between the two. One is on 192.168.124.110 and the other on

192.168.124.111, firewall outside is 192.168.124.1.

Can I use CEF or other method to alternate via the .110 and .111 interface for the same destination net ?

Any help/guidance appreciated. FYI PIX is at 6.2.2ED and both Ciscos (26xx) on 12.1

I think You have to get a router with 2 serial interfaces on both ends of the connection and then load balance the serial links. In this solution You can disable ip route-cache on the serial interfaces and enable CEF to get the Processor load down. In this case the PIX only have one gateway to the destination net. There is some examples in the TAC if You look on BGP multihoming.
