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. + +Generic Network Virtualization Encapsulation (GENEVE) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Geneve is designed to recognize and accommodate changing capabilities and +needs of different devices in network virtualization. It provides a +framework for tunneling rather than being prescriptive about the entire +system. Geneve defines the content of the metadata flexibly that is added +during encapsulation and tries to adapt to various virtualization scenarios. +It uses UDP as its transport protocol and is dynamic in size using extensible +option headers. Geneve supports unicast, multicast, and broadcast.
