[c-nsp] QinQ on NS-OX/Nexus

[James Bensley]

Yeah TAC have confimred it is not possible. The only way is to use a
looped cable between two ports but with a carrier NNI and many end
sites comming in to the DC each over QinQ it would mean a looped cable
(and thus 2 ports used) per end site (per S-VLAN) so it's a no go
basically.

I was hoping the I was hoping the "encapsulation dot1q X second-dot1q
Y" syntax would be supported so maybe we could at least use
sub-interfaces facing the carrier but no.


Cheers,
James.
