[c-nsp] Interworking Question

[Nick Griffin]

SP Gurus, I have a short term need to provide connectivity between a couple
endpoints for a migration. Customer currently has a DS3 with PPP encap
terminating in an edge 7200VXR, and will be migrating this service to
ethernet and terminating in new router. Wondering if it's possible to use
interworking on the existing terminating router to convert the ppp to
ethernet and hand this connection off via ethernet to new router. Seems
like it would be some sort of combination ATOM and Local Switching, but I'm
not sure it's even possible.

Interworking would be done on RTR1 below:

pppcircuit<->Ser1/0_RTR1_Gig0/0<->Gig0/1_RTR2

Thanks for entertaining.
