> Ethernet Virtual Private Network (EVPN) provides a unified control-plane that solves the Network Virtualization Edge (NVE) auto-discovery, tenant MAC/IP dissemination and advanced features required by Network Virtualization Over Layer-3 (NVO3) networks. EVPN is a scalable solution for NVO3 networks and keeps the independence of the underlay IP Fabric, i.e. there is no need to enable PIM in the underlay network and maintain multicast states for tenant Broadcast Domains. This document describes the use of EVPN for NVO3 networks, discusses its applicability to basic Layer-2 and Layer-3 connectivity requirements, as well as advanced features such as MAC-mobility, MAC Protection and Loop Protection, multi-homing, Data Center Interconnect (DCI) and much more. No new EVPN procedures are introduced.
