I want to take a bunch of VLANs from an interface, trunk them through my network, and spit them out on another end. Sounds like simple Q-in-Q to me.
Problem is one end is a 3600X, and the other is a 4900M. The 4900M is simple. The problem I have is with the 3600X and the EVC. Let's say I want to take VLAN 10 from a customer, and carry it on my network as VLAN 100. I will take them from a port on my 3600X and then carry VLAN 100 along with another bunch of unrelated VLANs through my network.
Can I configure a service instance on the customer facing port encapsulating their VLANs (let's say VLAN 10 for this example), then carry the internal VLAN (100) through on my trunks?
This doesn't work. I've tried various configs on the 3600 but can't get it working. I am not sure how to config the EVC properly - on the 3600X I suspect I also have to configure a service instance on the trunk facing into the cloud? This unfortunately isn't preferable as I want this to function as a basic, normal trunk (it has about 50 other VLANs on it).
