Yes, I agree, and we have done that. How about peering partners - which is our case this time. Is it feasible to maintain strict inbound prefix filters for all peering relationships?
To be honest, not really. Some countries I know do this for their exchange points. But by-and-large, it is not scalable. Same goes for AS_PATH lists for peering. One can be liberal at peering points but have max-prefix as a basic protection mechanism (which is what we do). Of course, IRR's are the other way to go. Mark.
