Overview on VXLAN



VXLAN

(Virtual Extensible Local Area Network)


Logical Switch reproduce switching functionality (Unicast, multicast or broadcast) in virtual environment which completely decouple from underlying hardware.

Logical Switches are similar to VXLAN in that they provides network connections to which you can attach virtual machine. The VM's can communicate with each other over VXLAN if they are connected to some logical switches.
