Is it possible to configure trunk interface to be Q in Q on client side, so all client packets get tagged twice?
Here is our situation - our service provider gave us several VLANS and we are using dot1q trunks with them. But, since it's different organization, we do not want to participate in their VTP and also we want to have independent VLAN database.
In general, we could, of course set up intermidiate swithes at each point and pretend they are provider swithes and create classic scheme, but that would be waste of dosen switches.
The service provider setup described is quite different of a tradition LAN extension service.
With the LAN extension service is possible to send tagged and untagged traffic through the link.
How is the line delivered? with Ethernet RJ45 at both ends? You have one physical port per VLAN? Or one port with some number of VLANs enabled? If this is the case, can you map VLAN numbers of you LAN with providers VLANs?
