NVGRE: Network Virtualization Using Generic Routing Encapsulation
RFC 7637, “NVGRE: Network Virtualization Using Generic Routing Encapsulation”, is an Informational document published in September 2015 by P. Garg, Y. Wang. The canonical text is published by the RFC Editor.
Abstract
This document describes the usage of the Generic Routing Encapsulation (GRE) header for Network Virtualization (NVGRE) in multi-tenant data centers. Network Virtualization decouples virtual networks and addresses from physical network infrastructure, providing isolation and concurrency between multiple virtual networks on the same physical network infrastructure. This document also introduces a Network Virtualization framework to illustrate the use cases, but the focus is on specifying the data-plane aspect of NVGRE.
