NVGRE (Network Virtualization using Generic Routing Encapsulation) is a network virtualization method that uses encapsulation and tunneling to create large numbers of virtual LANs (VLANs) for subnets that can extend across dispersed data centers and layer 2 (the data link layer) and layer 3 (the network layer).
Key capabilities of the NVGRE standard include identifying a 24-bit Tenant Network Identifier (TNI) to address problems associated with the multi-tenant network, and using a Generic Routing Encapsulation (GRE) to create an isolated virtual Layer 2 network that may be confined to a single physical Layer 2 network or extend across subnet boundaries.
