People keep saying this and I don't think they mean it. "ROUTING" is
never turned off on host doing IP (at least I can't think of a counter-
example). Your average host probably has a default route, it has a loopback
route, lots of hosts have a m-cast route, etc. Multihomed hosts are always
going to have even more complicated routing tables.

I think you mean, "if FORWARDING is switched off..."
