[cisco-bba] L2TP (PPPoA/E) aggregator

[Anastassios Chatzithomaoglou]

We are using a 7206VXR (NPE300 - 12.3.1a) for terminating L2TP sessions.
These sessions are coming through L2TP from 2 ATM interfaces, so there are no 
fragmentation issues.

We also use CAR on every virtual interface but we can't use CEF, since there is bug 
(CSCea34500) which annoys us.

The cpu load is around 40%, when we have 350 sessions.

What would be the next logical solution?

1) NPE400
2) NPE-G1
3) 6400

If i use more than one NRP on the 6400 will i be able to support more L2TP sessions?
For example 1 NRP = x sessions => 2 NRP = 2x sessions and so on....
