We have done this before in a pinch. We labeled the port descriptions as "QinQ magic" so other people wouldn't mess with them. Then we were able to get a 4948 dedicated for the QinQ part and our 6509 just did the regular trunking and routing again.

I'm considering it :-)  Just need to see and decide on what the best
approach would be... All our "magic" as you put it, would need to
happen on 6509's, but as you said - I'm sure it's doable...   At least
I have the answer I was looking for in terms of HOW to QinQ, hehe

Many thanks guys - really fantastic list this...
