Edison,

Will this work if you had a multipoint subinterface at the hub instead of a physical interface?

You can work the way you want, only the L2 - L3 mappings should be perfect.

multipoint subinterface has the same behavior as a physical main interface, the only difference is that you can have multiple multipoint subinterfaces while you can only have one physical interface.
