22.1 VXLAN Introduction
Virtual Extensible LAN (VXLAN) is a networking technology that encapsulates MAC-based Layer 2 Ethernet frames within Layer 3 UDP packets to aggregate and tunnel multiple layer 2 networks across a Layer 3 infrastructure. VXLAN scales up to 16 million logical networks and supports layer 2 adjacency across IP networks. Multicast transmission architecture is used for broadcast, multicast, and unknown unicast traffic.
