Re: What is multihoming was (design of a real routing v. endpointid seperation)
I believe RFC1122 was written in the days when there was a one-to-one correlation between IP addresses and interfaces, and, you couldn't have one machine with multiple addresses on the same network. Obviously, also, we are talking about network multihoming, not host multihoming in a NANOG context. It is hard to perceive a situation where Host Multihoming would require coordination.
