[j-nsp] Can I do "dumb" Q-in-Q switching on Juniper MX?

[Aaron Dewell]

You could do this over CCC on an MPLS core for sure (take the whole port not logical interfaces).  If your core is q-in-q though, you can configure your customer vlans as a range instead of a single number.  That potentially creates issues if multiple customers on the same SVLAN are using the same CVLAN id.  However, if you use a single SVLAN per customer, then there's no issue.

I'd say it's easier to do this using CCC but YMMV.
