One question about this, the Q-in-Q tunnelling would have to take place on the switch connected to the ring - what happens if the packet has already been placed in a dot1Q tunnel? I haven't really worked much with dot1Q tunneling - are their any know problems with extra tags? (aside from MTU issues, but I imagine most rings will support at least 9bytes)
Most switches will only see the outer tag and will thus be transparent for Q-in-Q:ed packets. -- Mikael Abrahamsson email: swmike@swm.pp.se
