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

[Mack McBride]

7600 will do EoMPLS with lan cards (best bet is pseudowire mode) but there are caveats with vlan rewrite and things like that.
And of course the lack of support for Q in Q.

The only cheap way to do what you want is to use some other box to either do VLAN translation or place the traffic into EoMPLS tunnels. I am not actually sure whether the 7600 will do routed EoMPLS with LAN-cards, I have only tried that with a SIP-600.

ES+ will obviously do what you want as you mention, and ASR1k and ASR9k
can do the same.
