I know this is good practice, but only because I've heard lots of (very knowledgeable!) people *say* that it's good practice. So I just wondered *why*? :-) Is it just so you don't have to carry that external /31 to the real next hop in your IGP? I guess if you've got ten thousand exit points that wouldn't be desirable, but if it's just a couple of hundred say, is that such a bad thing? Or is there more to it than that?
