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.
This came up at NANOG, and, yes, while with ATM the PVCs bring the automatic ability of shielding one from unwanted traffic from a "non-peer", a provider **could** point default at one of his peers. There is nothing that can be done at the L2 level. We could, again as mentioned at NANOG, bring down the PVC upon the request of only one of the peers, ending the default situation, but this is reactive, and requires that the default scenario still be detected...
