Rob,
The BGP memory usage below adds up to about 35 megs. Of course the IOS
needs more for itself, but where do you get the 256 requirement? I've heard
that 64 is just a tab too small these days, so I was assuming 96 or 128 was
plenty for 1 peer. A couple of the route servers I looked at off of the
page below had 128 meg ram, a full table, and had 20 megs free processor,
and 15 free I/O. Just curious...

This is a "sh ip bgp sum" from a Telia (as 1299) internet router in NY.
Per the line below, I would suggest at "LEAST" 256 meg if you only have 1
peer. And even then, if you have alot of filters and route-maps, you might
run out.
