Chris, W.R.T. #2 below: Be for real: No one ever suggested that backbone service providers attempt to ingress filter traffic -- this is an edge function.
I guess I'd add some clarification, though it should be obvious without.Backbone service providers who also sell edge circuits (e.g. dedicated T-1's to non-multihomed customers) ARE providing the edge function. A provider who claims "we're a backbone, so we should do no ingress filtering at all" is being disingenuous, at least for many of the largest networks today. I'm not accusing anyone of actually making such statements at all. I agree with Paul that this is an edge function, but that "edge" is a part of nearly every provider at some point in their businesses.
