[c-nsp] Need some help troubleshooting l2tpv3 tunnel

[Steven Pfister]

I've got a project I'm trying to use an l2tpv3 tunnel for. The tunnel seems to establish just fine, but it doesn't seem to do quite what I expected it to do. I'm trying to access vlans on a remote site that's connected via ATM. The remote side is connected by a 3640 router, plus a 8510 switch. On the local side, I've got another 3640, plus a 3500 switch.

As a possible clue, doing a 'show vlans' shows many packets output, but only a few input on the local side. On the remote side, the counts are zero in and out. 

Here is a piece of the config on both sides. There is a vlan 77 on the network connected to f0/0 on the remote side that I'd like to be able to assign to the network connected to f0/0 on the local side.

Thanks!
