+:abbr:`GENEVE (Generic Network Virtualization Encapsulation)` supports all of
+the capabilities of :abbr:`VXLAN (Virtual Extensible LAN)`, :abbr:`NVGRE
+(Network Virtualization using Generic Routing Encapsulation)`, and :abbr:`STT
+(Stateless Transport Tunneling)` and was designed to overcome their perceived
+limitations. Many believe GENEVE could eventually replace these earlier formats
+entirely.
+
+GENEVE is designed to support network virtualization use cases, where tunnels
+are typically established to act as a backplane between the virtual switches
+residing in hypervisors, physical switches, or middleboxes or other appliances.
+An arbitrary IP network can be used as an underlay although Clos networks - A
+technique for composing network fabrics larger than a single switch while
+maintaining non-blocking bandwidth across connection points. ECMP is used to
+divide traffic across the multiple links and switches that constitute the
+fabric. Sometimes termed "leaf and spine" or "fat tree" topologies.

+
+   :abbr:`VNI (Virtual Network Identifier)` is an identifier for a unique
+   element of a virtual network.  In many situations this may represent an L2
+   segment, however, the control plane defines the forwarding semantics of
+   decapsulated packets. The VNI MAY be used as part of ECMP forwarding
+   decisions or MAY be used as a mechanism to distinguish between overlapping
+   address spaces contained in the encapsulated packet when load balancing
+   across CPUs.
