QinQinQ :)

[lordi]

It's now an error in the title :)

We currently rent a 10 mbps link from a provider that we use as a lan extension. The provider supports QinQ which allows us to pass all of our vlans as it it was a big crossover between our switches.

There is another company in the same building with which we would like to share the link. They also need QinQ...

Is is possible to encapsulate QinQ in QinQ ?

If so, does a 3550 switch or a 7206 router could do that ?

Thanks

It is possible to create tunnel and use Q in Q. Only the main interface can be configured as an QinQ access gateway. Subinterfaces are then configured to specify the specific VLAN mappings.
