So a total of 240Mbps of BiDirectional traffic? Do you have ospf set to
passive for the virtual template? What is the LAC?

7200 (NPE-G1)
-------------

Input data
----------
2000 L2TP sessions terminated
netflow running on all input/output interfaces
ospf running
MQC (policy-map) per-user
no fragmentation problem
compression disabled
cef enabled
multicast (sparse) enabled on 5% of sessions
80 mbps input/30 mbps output traffic per interface (x2 for total)

Output data
-----------
CPU Usage = 45-50%

Question
--------
Is the 45-50% cpu usage normal/expected in our setup?

If yes, what would be the next step? 10000?
