Virtual Extensible LAN (VXLAN) lets you tunnel layer 2 traffic over a layer 3 network without the disadvantages of traditional layer 2 networks.

VXLAN, defined in RFC 7348 released in 2014, was originally a standalone technology and not paired with EVPN. It’s a data plane encapsulation that was designed to overcome the …

The VXLAN tunneling protocol encapsulates Layer 2 Ethernet frames in Layer 4 UDP packets, enabling you to create virtualized Layer 2 subnets that span physical Layer 3 networks. Each segmented subnet is uniquely identified by a VXLAN Network Identifier (VNI).

Virtual eXtensible LAN (VXLAN) is a network virtualization technology that 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 …

2024年11月25日 · VXLAN establishes a logical tunnel between the source and destination network devices, through which it uses MAC-in-UDP encapsulation for packets. Specifically, it encapsulates original Ethernet frames sent by a VM into UDP packets.

2020年3月30日 · So what is VXLAN and why does it seem so prevalent? Well simply put, VXLAN or Virtual Extensible LAN, is a tunneling protocol that allows you to connect two layer 2 segments together over a layer 3 network.

2024年2月27日 · VXLAN is a network virtualization technology developed to overcome the limitations of VLAN by allowing a single network to be used by various organizations. VLAN operates at Layer 2 and segments a physical network into multiple broadcast domains, while VXLAN operates at Layer 2 over Layer 3.

2024年10月15日 · VXLAN allows organizations to scale their network infrastructure, improve flexibility, and support multitenant environments in ways that traditional VLANs simply cannot. This article delves...

2025年2月12日 · VXLAN creates an extensible Layer 2 overlay network that can span Layer 3 network infrastructures via a 24-bit segment identifier. This is the VXLAN Network Identifier (VNI) which allows for up to sixteen million different network segments. How does VXLAN work?

VXLAN is the abbreviation of Virtual Extensible LAN. It is a network virtualization technology developed by Internet Engineering Task Force (IETF). Virtual Extensible LAN is an extension to classic VLANs (Virtual Local Area Network). It is basically a multi-point tunnelling technology.
