[c-nsp] L2TPv3 sizing?

[Howard Jones]

Can anyone point me to any documentation/whitepaper regarding router
sizing for L2TPv3 throughput? We're trying to understand what the
startup cost would be for a couple of ~100Mbit/sec L2TPv3
ethernet-to-ethernet tunnels as an alternative to a full MPLS solution.

Is there any Cisco (or 3rd party) information on what size routers would
be needed for given link sizes? My google-fu is weak on this.

Thanks in advance for any pointers,

Howie
