You could do it a couple ways. First, use BGP multihop inside your
network to connect all three routers. Second, use a tunnel to connect
them with normal BGP. Then, traffic will go out the best BGP route.

Hi,
You really didn't explain what issues you're experiencing in your test bed, but
it sounds like you want simple iBGP peering. You'd do something like this on
both routers.

Depending on who the two providers are, you have have to use different

The preferred way is to adjust local preference based on a route policy. You

You have ultimate control over the traffic leaving your network. You could

You can influence the traffic coming in by AS prepending, but it's

You can do bgp padding and other tricks. Part of it depends on if you are
