1.vxlan Virtual extensible LAN is a overlay network technology that uses the Mac in UDP method toLine package, a total of 50 bytes of encapsulated headers. 2.VTEP adds a packet header to the virtual machine's packet, and these new headers are removed after the data arrives at the destination Vtep. 3. The Vxlan data plane is a tunnel-based data plane because the Vxlan
