"reachable-via any" means you're only going to drop the packet if you
don't have *ANY* route back to them. I think that if you're in a situation
where you have asymmetric routing, and have a packet coming in on one path
that you theoretically COULD send to the destination, and the destination
has an alternate-path route back to the source, *but you don't have ANY route*,
then you're already in a "broken" state anyhow.
