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.

Re: From: George William Herbert <gherbert () retro com>
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.

        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/...
