[cisco-bba] Maximum PPPoE subscriber on 7200VXR-NPE-G1

[Clayton Zekelman]

We tend to run our NPE-G2 based routers at around 3000 sessions just to keep some headroom.

Interestingly, the performance seems to vary based on how the sessions are coming in.  When we were using PA-A3-OC3 interfaces (4 per router), the CPU utilization was significantly higher than when we migrated the traffic to GigE interfaces.

Presumably this is because the traffic comes directly on to the NPE card through the built in interfaces rather than having to traverse the PCI bus to the PA cards.
