There is no way not to use global VLAN space in 7600. For QinQ interfaces
ES20 allows mapping them to internal global VLAN-ID, so you can have same
QinQ set in another interface.
ES+ allows this for single tagged interfaces also, giving you illusion of
no global VLAN space.

In ES20 if you want same Q in two interfaces, you must use EVC +
bridge-group, it will never get support for single Q<->internal VLAN-ID
mapping.
