In short, VXLAN is a Layer 2 overlay scheme on a Layer 3 network. Each overlay is termed a VXLAN segment. Only VMs within the same VXLAN segment can communicate with each other. Each VXLAN segment is identified through a 24-bit segment ID, termed the "VXLAN Network Identifier (VNI)". This allows up to 16 M VXLAN segments to coexist within the same administrative domain.
