[c-nsp] Bridging ATM on 7206? (Getting really frustrated here)

I think so, yes. I suppose an ATM switch can deal with sending cells
out the same physical interface that they came in on, at least I hope
so. The problem is that I do not have an ATM switch :-( If I'd known
there would be a problem five months ago, I could *maybe* have bought
one and set it up :-( Even if I did buy one now (how much could one
ATM switch with at least two STM SMI interfaces cost?) I'd have to
wait a week or so to set up a planned service disruption for all those
*other* clients who are happily using L3 services over that ATM link.
Getting the operator of the ATM switch on the other end to bridge will
be extremely difficult, lengthy, and expensive (at least a thousand
dollars for something that has to be a ten-line config change, yes, I
know, but they're the only game in town and not expensive as long as
you don't deviate from the norm).

I just can't believe a 7200 can't do this. I can't get a definitive
response either way from the Cisco docs. Anyone? Please?
