Any reasonably valid way of predicting when we'll hit 244,000 routes in the default-free zone?
Um?

Unlike Y2K, the end of the useful service life up the Sup2 can easily be pushed further away in time.

Autonomous System There's really only 151129 routes you need to have "full routes". Forcing just these top 4 slobs to aggregate reduces your global table by 3619 routes. Forcing the top 30 to aggregate frees up 15809 routes. Of course there are other reasons to upgrade (better CPU, MPLS, IPv6, etc.), but if you can't upgrade, there are alternatives to stretch the old hardware. It's not like it hasn't been done before. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
