I did some basic checks (i.e. full 143k table load from quagga peer),
with 2851 equipped with 256MB of RAM.

It works OK, but BGP *is* CPU intensive - every 60 seconds BGP scanner
has to walk thru the table, which produces spikes even on 7206/NPE-G1.
It may be not noticeable if everything works smoothly, but when the
trouble happens, Your router will go CPU-crazy ;)

But, of course, if You're planning to run BGP but the only option
is something ftom the 2600/2800 line, I would go for 2800.
