Hi Matthew,

Cisco routers forward packets for 127.0.0.0/8 unless explicitly
configured not to, treating it like any other unicast address.

Linux load balancers require a special kernel patch to also use them
as routers because the kernel authors failed to conceive of a
situation where accepting an external packet with a source address
matching a configured interface address was, in fact, a correct thing
to do.

I vote for the Cisco approach. It has occasionally quirky results but
it's also flexible enough to handle situations the protocol designers
didn't conceive of.

Bill Herrin
