Dampening is done on the eBGP router where the route enters the AS, and, unless I'm mistaken, per route/path and not per prefix. So the flapping that ISP A sees from ISP B is a completely seperate thing from the flapping that ISP A sees from its customer's customer as far as the dampening algorithm is concerned. > Should we change the subject (back) to "BGP to doom us all"? For all the criticism that BGP is subjected to, I find it curious that nobody has proposed a replacement protocol (that I'm aware of).
