VXLAN Insights

What is VXLAN?

VXLAN (Virtual Extensible LAN) is a network virtualization technology that encapsulates Layer 2 Ethernet frames within UDP packets, enabling the extension of virtual networks across Layer 3 infrastructure. It is commonly used to create large, scalable virtual networks in data centers, allowing for workload mobility and network segmentation.
