The current routing model doesn't scale. I don't want to sit 5 years from
now needing a router that'll handle 8 million routes to get me through the
next 5 years of route growth.
PI space for multihoming and AS number growth is a bad thing for scaling
and economics, however you look at it.
Shim6 would hopefully curb the prefix growth very early in the growth
curve as single entities won't need AS to multihome between two different
ISPs.
I do believe in a completely new solution for multihoming than what we
have today, shim6 is the first I've seen so far, I'm open to other
suggestions though. Current way of doing it (AS+PI) gives me the creeps
when I extrapolate into the future.
