[c-nsp] L2TPv3 sizing?

[Rens]

Have a look at Cisco Routing Performance sheet.

This already gives you an indication of the speed with 64 byte packet sizes
without L2TPv3.

The second think you need to make sure is that the router does not fragment
any of the big packets. I have only been able to test this with 7206VXR
platform, not sure how well other routers handle fragmentation.

I have already seen speeds of 300Mbps+ with L2TPv3 tunnel with 2x 7206VXR
NPE-400 (with 1024-1522 frame sizes)

I guess if you want also that speed with 64 byte you will have to need
NPE-G1.

Subject: [c-nsp] L2TPv3 sizing?

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
