[cisco-bba] RedBack comments

[Andy Schutz (aschutz)]

Mark,

I can't speak to whether anyone has 16k (or even greater than 10k)
sessions up on a production router.  I think the 16k number is a
"marketing" number but the reality is that you can get 16k sessions up
and active and passing traffic on a 7206 with NPE-G1.  All vendors are
guilty of giving the absolute system maximum that a platform can support
under best case scenarios.  For instance, Redback quotes 8k users on the
SMS 1800 but I think you will more commonly find numbers like 4k in
production.  I believe they can do 8k, but people running production
networks don't want to have their routers maxed out and on their last
leg.  So in Cisco terms, what level of CPU are you willing to be happy
with?  Everyone has a different answer for this and the level of CPU
that you will run at is also not just a function of the number of users,
but also any services you have enabled, routing protocols, ACLs, etc.

I hope that helps a bit.

Cheers,

Andy
