Ah, now I understand. I read your mail in a different light, like
"I want to write a BGP implementation and I want to know how big my
buffers should be". Which explains my response :-)
As to your original question: sorry, I have no idea. A way to test this
might be "connect two really fast routers, one of them having the
full BGP table (>100.000 routes) and a really bleeding edge IOS (12.2T
has lots of BGP changes)" - and if you can't see any larger packets then,
assume that Cisco never sends larger packets. But this is no guarantee
for anything...

Sorry, nothing.
