What happens when you have 2 inner vlan's with the same ID, but different outer IDs? Or is that not a normal deployment scenario?

[jlucovsky]

Good point.  It’s a customer issue and they must be aware of that possibility. The customer requested this as they are incorporating a legacy network where the inner vlans are unique across the total deployed vlan range.

Should the doc bring that point up more strongly?

Should this have min-version: 8 ?
