A Network Virtualization Overlay Solution Using Ethernet VPN
RFC 8365, “A Network Virtualization Overlay Solution Using Ethernet VPN”, is a Proposed Standard document published in March 2018 by A. Sajassi, J. Drake, N. Bitar, R. Shekhar, J. Uttaro, W. Henderickx. It has since been updated by RFC 9746. The canonical text is published by the RFC Editor.
Abstract
This document specifies how Ethernet VPN (EVPN) can be used as a Network Virtualization Overlay (NVO) solution and explores the various tunnel encapsulation options over IP and their impact on the EVPN control plane and procedures. In particular, the following encapsulation options are analyzed: Virtual Extensible LAN (VXLAN), Network Virtualization using Generic Routing Encapsulation (NVGRE), and MPLS over GRE. This specification is also applicable to Generic Network Virtualization Encapsulation (GENEVE); however, some incremental work is required, which will be covered in a separate document. This document also specifies new multihoming procedures for split-horizon filtering and mass withdrawal. It also specifies EVPN route constructions for VXLAN/NVGRE encapsulations and Autonomous System Border Router (ASBR) procedures for multihoming of Network Virtualization Edge (NVE) devices.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
