I'm looking for a sizing guide for the ISR's that would indicate what the overhead of L2TPv3 would be.
I'm familar with the router performance guide with the PPS figures, but I have never seen a guide that quotes what the services overhead would be.
My requirements are something that will provide at least 20Mb full duplex of L2TPv3 throughput. There will be no other services running. The two routers will be connected by a 100Mb L3 service.
I'm hoping that the 2811, or maybe even the 2801 might be up to the task.
Any info anyone could provide would be great.
