I'm currently seeing ~100 prefixes originating from 4761, and an additional 725 transited through 4761. This would not be difficult to handle with prefix lists, assuming some level of automation.
Indeed. I, for example, have an upstream that filters only on AS_PATH. Naturally, we are quite aggressive and insistent about filtering both on AS_PATH and prefix list across interconnects to our downstreams, but if things were to blow up on our side, the upstream in question would not be protected (unless, of course, they are relying on "max- prefix" as well). Mark.
