Hi, In this case L2TPv3 would be the best option, but I don't think Cat65xx support L2TPv3 till date. now you can think about EoMPLS l2 vpn to exchange ethernet frames between sites.
quick look ethernet over MPLS example : http://fengnet.com/book/MPLS%20Configuration%20on%20Cisco%20IOS%20Software/ch11lev1sec2.html Thanks Ramesh On Mon, Jan 3, 2011 at 4:23 PM, John Neiberger <[email protected]> wrote: > I've never had to configure any sort of layer two tunneling, so I'm > not really familiar with my options.
