> Lots of the switches support QinQ, e.g. 3550, 3650, 3750, 6500/7600.

And what about routers?

The scenario would be:

    | .1q customer trunk
+------+
| 3550 |
+------+
    | q-in-q trunk
+---------+
| 7206VXR |
+---------+
    |
(L2TPv3 cloud)
    |
+---------+
| 7206VXR |
+---------+
    | q-in-q trunk
+------+
| 3550 |
+------+
    | .1q customer trunk

I am not sure that the routers need to explicitly support QinQ, maybe they
will just encapsulate whatever they see coming on their .1q subinterface? I
am probably being too naïve here...
