Hello. I have two 1941 routers with ipbasek9 license and each has, EHWIC4ESG, EHWIC-4SHDSL-EA, and two GigE ports. I'd like to configure ATM and keep it L2 and only have an IP on the router for management or SVI if needed. The intent is to connect one to the existing LAN via a trunk then extend existing L2 over the ATM down to the end user and printer. The routers are essentially physically connected as their is no service provider I'm dealing with.
I've looked at L2TPv3, bridging, local switching and can't get anything to work and would like to refrain from purchasing a datak9 and seck9 licenses. Is this possible with the current license and/or does anyone know of a simple ATM configuration for this? Thanks.

mlund,
Hello. Wanted to say thanks for the insight. I'm not too sure what I was missing, but configured the devices similar to what you posted and so far have been able to have two different vlans at the end user location send/receive traffic and get an IP from the dhcp server. Thanks again.
