Fast Ethernet WAN Trunking
Hi,
We have a 100 mbs fast ethernet wan line over our service provider connected to layer 3 router on both sides. For a design I want to connect this line to a layer 2 switch at both ends and do vlan trunking across it (for a vmware stretch vlan). As it is a ethernet layer 2 line is a matter just plugging in each side and creating a trunk. I contacted my service provider the initial response they have said it is ?? But i want a second opionion as i was under the impression to do this we would have to have a line that supports qinq to go over the sp overlay network. They do have another specfic qinq product on there website i am just questionating whether the information given to me by their repersentive is correct and his not mistaken

I agree, the service you would need is a QinQ service; the reason for this is, the current handoff to you is already a member of a vlan in their infrastructure, to tag additional vlans would require a protocol that is capable of encapsulating a trunking protocol into another trunking protocol: IEEE 802.1ad (Dot1q tunnel). You could however, utilize a pseudowire endpoint to accomplish something similiar, but it will not allow you to create a trunk.
It will require additional overhead (operationally and administratively).
