Re: Dot1q trunking over L2TPv3 not working - urgent help needed

Irfan,
Check out both of these links, they give you a really good examples (i think
they are using switches):

Your configuration has couple of issues. For one if you are trying to have a
trunk, your interface on the router with pseudowires is not setup to be
802.1q tagged, you would need to create a subinterface and set the
encapsulation on it. I think this should give you enough info to find out
the rest.
