You'll need:
. to turn on promiscuous mode on the vCenter port group where is connected the ToR interface-VLAN (since the VM-ToR will send packets from other sce-mac@ than its mac@)
. to have the ToR vendors bits in VM form factor with HW VTEP support)
After that, you're good to go :smileyhappy:
Note: Obviously don't test perf since you'll have "promiscuous mode" enabled.
