Looking at the routing tables you see failures. 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.
Yes, to clarify, by "completely and utterly" i mean not just
the prefix that you saw drop, but more specific and more general routes
that you may have access to as well.
