My thought process is as below.
I wanted to extend the VLAN A which is currently configured in the Physical L3 switch.
I will extend this VLAN into the ESXi hosts where the NSX are configured. But I will not configure VXLAN for this.
It will be VLAN A with distributed port group.
The D.G will be the physical L3. Its like a simple L2 extension into my ESXi hosts or clusters which are part of NSX.
Let me know if this is correct and can be achieved ?
