Use the loopback address on each of the two routers as the bgp origination address and make sure that your router has a route for the loopback address of the far router going over both of the GigE links. Ciscos handle this fine. Others can as well. YMMV. Walt ----- Original Message ----- From: dan <deearekay@gmail.com> Date: Monday, May 7, 2007 10:09 am Subject: Load balancing To: nanog@merit.edu
Hello, I currently have 2 routers with a single gigabit link (and correspondinginternal BGP session) between them. router1 <---------gigabit------->router2
Simple setup. Now that we have reached the limit on this gigabit link, we are adding a second gigabit link between the same 2 routers, and we wish to load balance across them. Traffic is about 5:1 ratio of out:in. router2 has bgp sessions with several upstreams, and router 1 has bgp sessions withfurther internal routers. What is the best way to balance across these 2 links?
