Hi All, Q-in-Q is a service provider feature and is not supposed to be used by end-users. Q-in-Q is a solution for metro Ethernet providers to use their own VLANs while respecting customer VLANs. The main support has to come from switches deployed by service providers. I believe that end-hosts should not have this capability and only service provider routers should have this features. Ofcourse, this does not mean that people should not use the capability once it is there. -- Srikant
