L:2TPv3 and vlans

I'm trying to gain access to vlans at a remote ATM-connected site and assign them to ports on a switch at a central location. I need to do this for about 10 remote sites, one at a time. I was told that L2TPv3 was a good thing to use for this. Now, with much help, I've got an L2TPv3 tunnel set up between the 3640 at the remote site and a 3640 plus 3550 switch at the central site. The tunnel is established, but nothing seems to go through it.

Has anyone used 802.1q vlans with L2TPv3 tunnels like this? I'm sure it has to be something simple that I've forgotten about...

Thanks!

Re: L:2TPv3 and vlans

In L2TPv3, Ethernet Xconnect supports port-based VLAN membership and the reception of tagged Ethernet frames. A tagged Ethernet frame contains a tag header (defined in 802.1Q), which is 4 bytes long and consists of a 2-byte tag protocol identifier (TPID) field and a 2-byte tag control information (TCI) field.

Refer the following url for more information about using 802.1q vlan with L2TPv3 tunnels:
