In article <199507012057.QAA26175@duality.gnu.ai.mit.edu> you write: > HOSTS DO NOT NEED ROUTING INFORMATION. >What would you suggest that multihomed hosts do? He admits that *they* need routing information; what he doesn't consider is that all hosts on any network with more than one router needs routing information too, even though the host isn't multihomed. I disagree. First of all, he said that only `gateways' need routing information, and multi-homed hosts are not (necessarily) gateways. Secondly, it *is* plausible for single-homed hosts to rely on multiple routers negotiating shortest paths and sending redirects -- provided that there is a router discovery protocol so you don't get screwed when one router goes down. However, this still leaves multi-homed hosts with inefficient and possibly incorrect routing.
