Re: how is cold-potato done?

I guess the final question is -- why is anyone concerned about best-exit at all? Doesn't shortest-exit still get the traffic there? I'm willing to bet there are a lot of different answers to all these questions.

Some networks will supposedly relax their peering requirements if you do best-exit. Also, for some networks shortest-exit results in pipes with large traffic flows in one direction and not the other, so using best-exit may not require any increase in backbone capacity. -Ralph
