[nsp] PPPoE LNS - Redback, Juniper, or Cisco?

[Corbett Nelson (cornelso)]

You can run up to 16k active sessions on the 7200 with the NPE-G1. The
software for the 7200 supports virtual sub-interfaces as well now which
allows the much greater scalability of interfaces. The 10000 ESR will
scale up to 61500 sessions if you are looking to jump up to the next
tier.

Hi Jay 

Just my experience with c7200 as LNS for broadband aggregation. With a
NPE-300 you can run safely arround 2000 users. Ensure, that you don't
hit any MTU (don't fragment packets!) and Virtual Interface (use
pre-cloning!) 
problems - both can consume a lot of CPU cycles. 

With a NPE-G1 you should be able to run arround 3000 users. So, one 7200
cannot handle all users you currently have on one SMS... 

cheers,
michel
