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?


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