It uses a VLAN-like encapsulation technique to encapsulate OSI layer 2 Ethernet frames within layer 4 UDP datagrams, using 4789 as the default IANA-assigned destination UDP port number. VXLAN is an evolution of efforts virtual lan technology pdf standardize on an overlay encapsulation protocol. It increases scalability up to 16 million logical networks and allows for layer 2 adjacency across IP networks.
The VXLAN specification was originally created by VMware, Arista Networks and Cisco. Other backers of the VXLAN technology include Huawei, Broadcom, Citrix, Pica8, Cumulus Networks, Dell EMC, Mellanox, FreeBSD, OpenBSD, Red Hat, Joyent, and Juniper Networks. VXLAN was officially documented by the IETF in RFC 7348. 1ad, an Ethernet networking standard, also known as provider bridging, Stacked VLANs, or simply QinQ.
