Right now we're running BGP internally, and the routes that are being chosen based upon the final BGP decision step or what I like to call the 'IP address tie breaker' which is not always optimal. We have a cisco 7500 that is connected to 4 other Cisco 7500s which each have 45Mbps ds3s to the Internet, we would like to load balance the outgoing traffic across all 4 of these 7500s, can anyone shine any advice my way? I noticed that there are instructions on Cisco's site regarding doing LB on 12000s.Load balancing with BGP is the same on any cisco router. Are you doing BGP with the routers on the other side of those DS3s? If you are, you will need their help in load balancing properly. Get them to allow you peering with a loopback interface and use equal cost static routes to do the load balancing to that loopback interface.
