Top Overlay Networks Widget
Virtual Extensible Local Area Network (VXLAN) represents a technology that enables you to segment your networks (as VLANs do), but that also solves the scaling limitation of VLANs and provides benefits that VLANs cannot. VXLAN is often described as an overlay technology because it enables you to stretch Layer 2 connections over an intervening Layer 3 network by encapsulating (tunneling) Ethernet frames in a VXLAN packet that includes IP addresses.
