Re: Full BGP and memory

        I'm able to squeak by w/ 128M in my 7200 running full tables
(with two feeds) and cef enabled.

        I would recommend getting a VXR upgrade asap and upgrading to 256M
incase something ugly happens like a bunch of prefixes get leaked to you
by a upstream/peer and suck up a lot of your memory.
