Maybe your upstream sets the NEXT_HOP to your side of the point-to-point for
you, just in case you neglected to do so.
Even if they don't, who's to say what's unreachable? If the NEXT_HOP is
truly unreachable, in that there is no route to it, the BGP path won't be
marked as valid and won't make it to the IP routing table (Loc-RIB.)
I've long felt that IP should have come with a provision for an address that
is never routed. It would be great if we could get something like 127.0.0.2
for this very task.
