You do not need to do interworking on the router because interworking is
being done by qwest on their network. From the router's perspective, it
looks like a frame circuit and an ATM circuit.
Qwest requires interworked frame circuits to be IETF encapsulated, so your
FR interface would look like:
encaps frame-realay IETF
ip address .....
frame-relay interface-dlci 16
I also beleive Qwest uses snap encapsulation on their ATM with ilmi
disabled, so you would have
no atm ilmi-keepalive
ip address ...
pvc 1-0-47 4/47
The 1-0-47 is the VCD, which you can adjust to any value you please as long
as it is unique on the router. Adjust the ubr and value to whatever the
circuit is actually (since you did not provide that info)
Let us know if any of this helped
