[c-nsp] how many maximum BGP routers can be to reside in one AS？

[Keegan Holley]

Not that I'm aware of.  BGP doesn't require the same computations as an IGP
so it's almost limitless.  iBGP isn't much different than eBGP in the way
routes are calculated from the perspective of what you are trying to do.
 The bottleneck is almost certainly going to be the amount of RAM in your
boxes.  No matter what you decide the best thing you can do is create a
through IP addressing and summarization plan.  Have you looked
at separate AS's instead of confederations.  They will allow you better
control of traffic.  There are some design issues with AS-confed.  Anything
with that many routers should be very interesting.  Best of luck.
