[nsp] ATM Route Bridge Encapsulation

From: Jay Stewart (cosmo@olywa.net)

I'm moving a DS3 that carries DSL terminations (ATM PVCs) that are a
combination of IP routed, bridged (with separate BVI), and bridged (shared
BVI), from a 7200 running 12.0(7)T to a 7507 running 12.1(5)T and I want some
advice, and a configuration double check. For my own personal mental health
reasons, I don't want to have to reprovision by hand 400+ ATM PVC's *after*
making the router switch because I didn't have the config right, so If you are
familiar with this feature (and IOS syntax), I would appreciate a quick look
see to make sure I'm not doing this wrong.

Is my head in the right space here? Thanks in advance, (and a beer or two
gratis the next (first?) time we meet), for whoever can help me double check
this configuration.
