Hello,
I currently have 2 routers with a single gigabit link (and corresponding internal 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 with further internal routers. What is the best way to balance across these 2 links?
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.

Depending on the platforms, etherchannel/port-channel would be a fairly
straightforward solution.
