VxLAN is an encapsulation protocol that provides data center connectivity using tunnelling to stretch Layer 2 connections over an underlying Layer 3 network. In Datacenters, VxLAN is used to create overlay networks that sit on top of the physical network, enabling the use of virtual networks.
It uses a VLAN-like encapsulation technique to encapsulate OSI layer 2 Ethernet frames within layer 4 UDP datagrams. VxLAN endpoints, which terminate the VxLAN tunnel, may be either virtual or physical switch ports, which are known as VxLAN tunnel endpoints (VTEPs).
