Thanks a lot for the useful information. I know the TEP (VTEP previously 
), but I never understood what does the guide mean by saying "the edge must use a different overlay TEP VLAN than used by ESXi....".
One more thing please, the design guide says that the cluster is a "compute and edge shared cluster", however, to my understanding, it's not possible, or not recommended to have the edge VM on a NSX-T prepared ESXi host, if this is correct, then, should we dedicate or use existing hosts with only traditional virtual switches? but what if the host has plenty of physical nics, can I host it on a host that has N-VDS, as well as VSS, or VDS?. The design guide didn't clarify that point.
Thanks,
