Virtual extensible local area network (VXLAN)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The purpose of VXLAN is to provide scalable network isolation. VXLAN underlay
can spread over two or more layer-3 network domains. It allows an overlay
layer-2 network to spread across multiple underlay layer-3 network domains.
The purpose of VXLAN is to provide scalable network isolation. VXLAN is a
Layer 2 overlay scheme on a Layer 3 network. It allows an overlay layer-2
network to spread across multiple underlay layer-3 network domains. Each
overlay is termed a VXLAN segment. Only VMs within the same VXLAN segment
can communicate.
