but reachability is what it's all about. the folk here are paid to deliver packets. the control plane (routing) is one of the tools we use to achieve that end.

If a prefix goes away completely and utterly, and is truly unreachable, then anyone trying to see it is going to see an outage.not if a covering or more specific tells us how to get packets to the destination. but perhaps that's what you mean by a prefix being unreachable and i am being too picky.
would that be that -all- your neighbors have no information on how to forward that packet, then the destination is unreachable. what if a neighbor lies about reachablity and you dump your packets into their "blackhole"? that darned policy-constrained routing ick can be tough to deal w/...
