[c-nsp] 1200 L2TPv3 session on 1 router

[Tantsura, Jeff]

I perhaps didn't ask my question clearly enough.
I need to terminate 1200 P2P L2TPv3 VPN's aka L2 over IP (xconnect).

I know, PWE3 over MPLS would be the right solution but I have to stick
to plain IP.

Jeff

It depends ;)

With short-living dialup vpdn-sessions the virtual-access interface
creation and ppp/radius-negotiation will consume the majority of CPU
power (whereby precloning will help here). With solid broadband
DSL-lines the kpps de/encapsulated and not the bandwidth is what you
calculate on software based 7xxx series.
