One can point default at someone whether or not they are peering with the person. I am somewhat confused by the thought that people believe that they need to be peering with someone to have that person point default at them. I could (I don't, but I could), point default at /anyone/ on the same switch fabric as me, whether they are peering with me or not. Why do people continue to tie these 2 issues together?

At the PacBell Nap for instance, you *couldn't* just point default at anyone on the same switch fabric -- because you need to set up a peering (mapping) within the switching fabric first, before you do any route peering. Until this happens there would be no unwanted traffic. -d
