Hardware VTEPS – Design Considerations

Remember that a logical switch with a lif on the DLR can not be extended using a HW VTEP. The GUI will not let you select that logical switch, therefore you have to create the lif on a ESG (Edge). This has an impact on traffic flow as now all VM to VM traffic that needs to be routed will need to traverse your edge cluster and that ESG which is not optimal. This needs to be carefully considered in your design.

Also remember that Universal Logical Switches can not be used in conjunction with a Hardware VTEP.
