[c-nsp] 802.1Q-in-Q VLAN Tag Termination on 7600/6500 OSN modules

The ES+ cards are the way to go.
The OSM modules aren't going to do what you want.
In addition they aren't properly supported in newer code.

Hello,

We have some 7603 boxes with SUP720/SUP2 installed as main supervisor in our MPLS Edge sites.

Now we need to terminate QinQ VLAN directly on one or more GE interfaces of the 7603 routers because we are planning to introduce metro ethernet tecnologies (ME3400E/ME3600X) in our fiber and microwave access network for reducing the VLAN configured between the switches located in the access network (now we have 1 VLAN = 1 Customer).

I see that 7600 catalyst modules doesn't support QinQ VLAN termination (the command "encapsulation dot1q outer-vlan second-dot1q inner-vlan) because they are "LAN" modules.

Is there anyone who tested QinQ termination on old 7600 OSN GE modules like the OSM-2+4GE-WAN+ ? If not supported the only way to support QinQ is to buy new (expensive) 7600-S chassis + ES cards or SIP-400 and SPAs V2 ?

In out network environment we have also some 7609-S(RSP720) with ES+ card located into the core an large aggregation sites and with this equipment we don't have problems because the QinQ Termination is supported on ES+ card.
