Hmm, I think it really depends on the characteristic of these 300
sessions. Do you receive four full feeds and send them to the 300
neighbors and receive fewer prefixes from these 300 neighbors? I don't
think this will be a problem, a test where an MSFC3 receiving one full
feed (200k) was able to converge in reasonable amount of time sending it
to 1000 neighbors. I guess it also depends on whether we can replicate
the updates (i.e. common outbound routing policy, etc.)...
