Applicability of EVPN to NVO3 Networks
draft-ietf-nvo3-evpn-applicability-02
Abstract
In NVO3 networks, Network Virtualization Edge (NVE) devices sit at
the edge of the underlay network and provide Layer-2 and Layer-3
connectivity among Tenant Systems (TSes) of the same tenant. The NVEs
need to build and maintain mapping tables so that they can deliver
encapsulated packets to their intended destination NVE(s). While
there are different options to create and disseminate the mapping
table entries, NVEs may exchange that information directly among
themselves via a control-plane protocol, such as EVPN. EVPN provides
an efficient, flexible and unified control-plane option that can be
used for Layer-2 and Layer-3 Virtual Network (VN) service
connectivity. This document describes the applicability of EVPN to
NVO3 networks and how EVPN solves the challenges in those networks.
