[c-nsp] Help with Q-in-Q Tunneling Hardware

[Garrett, Jason]

Yes, we need to terminate the QinQ.

In the example provided below, I'm assuming gi0/0 is the NME-16ES-1G service module, correct? One thing that I haven't fully grasped is how the service module works with the router.  I understand that I have to have an IP Address assigned to gi0/0 of the 3745 in order to connect to the service module and then interface gi1/0/2 of the service module is tied to gi0/0 of the 3745.  Does this mean that the gigabit physical port on the service module is gi1/0/1 of the service module, and if that is true, do the commands above need to be entered on the service module gi1/0/1 port or gi0/0 of the 3745?  Gi0/1 on the 3745 will allow the commands, but gi1/0/1 of the service module will not.

Thanks!
Jason

Do they mean 'terminate' a QinQ link or you tunnelling QinQ from one port of your device to another?

The 3745 with 12.4T can terminate a double-tagged packet on an interface like so:
in gi0/0.10
encap dot1q 10 second-dot1q 20
ip address x.x.x.x x.x.x.x


Thanks

> We are a service provider and just recently installed our first Ethernet uplink (we were all ATM previously). The ISP say that we need to terminate this connection to a router that supports Q-in-Q tunneling. We currently have a Cisco 3745 (running IP Services Version 12.4(15)T14) with a NME-16ES-1G service module. Should this be sufficient?
