Re: What is multihoming was (design of a real routing v. endpoint id seperation)

[Owen DeLong <owen () delong com>]

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.

If it wasn't crypto-signed, it probably didn't come from me.
