Tim,

I need basically 6 physical GE, but need to route L3 subinterfaces on 4 out of 6
of them.

The 2 remainning GEs only need to be either a p2p routed interfaces either
classic access vlan switchports (onto different vlan ID than the vlans that will
be tagged onto the L3 subinterfaces), so these don't have the problematic.
