I've got a device which requires stacked vlans (q in q/second dot1q). I've got a cisco 7507 as my router, and a 3750G switch. I think I've figured out that I need to combine them at the router level, but I can't find any documentation about how to do this on the 7507. Is this possible, and what's the minimum IOS version I need (I'm running 12.1(5)T12 at the moment.
Thanks for any help.
