Hello, As long as you adjust your switching MTU for 4 dot1q tags, things should work fine. We have a customer who is doing Q-in-Q on in our Q-in-Q already. I believe (but don't quote me on this!) you can have up to 8 layer 2 dot1q tags at once.

Is my only concern the additional 4 bytes that I have to add to the MTU size in all the switches it propagates through? Thanks for any help.
