Ramesh,

Your topology has a Layer3 link between offices so you need a router terminating the Layer2 tunneling.

You will be implementing a L2TPv3 design and you need a router for that. Any model should be able to provide this service. Depend on the size of the office, I suggest getting a 2800 or 3800 with multiple LAN interfaces. One LAN interface can be allocated for the LAN extension and the other LAN interface can be allocated for normal IP routing.

The command you will be using on the router interface is xconnect, please see:

for more info.

You will need a device at each location that supports some kind of Layer2 Tunneling. The C3500XL does not.

Do you know where I can read up on Layer 2 Tunneling?
