Q-in-Q configuration

[geustace]

We have a trunk being present from our NREN, it currently has 2 vlans on it 900 & 2101. We need to be able to encapsulate another group of local vlans and tunnel them through vlan 2101. I would like to do this on a single switch, probably a 6506 with Sup720 but am struggling to work out how one can actually do it.

Any pointers appreciated.

One of the prerequisites for IEEE 802.1 Q-in-Q VLAN Tag is that is must be connected to an Ethernet device which support

double VLAN tag imposition/disposition or switching.
