Jason,
I hope I understand your question, but VXLAN doesn't care where the Layer 3 interface is in physical network. You can think of it as moving the layer 3 interface to the VXLAN tunnel termination points, which reside in the virtual switch. The physical network is unaware of the VXLAN overlay. And the setup of the VXLAN and coordination with the edge switches where the VXLAN tunnels are terminated are automated through UCS Director. Hope that helps. - GK
