What is VXLAN?
VXLAN, or Virtual Extensible LAN, is a network virtualization technology that extends Layer 2 networks over a Layer 3 infrastructure by encapsulating Ethernet frames inside UDP packets. It was created to overcome the scalability limitations of traditional VLANs, which support a maximum of 4,096 network segments, by supporting up to 16 million virtual network identifiers. VXLAN is widely used in data centers and cloud environments where large numbers of isolated virtual networks need to coexist on shared physical infrastructure.
