Abstract

This document defines an Extended Community that is advertised along with an Ethernet Virtual Private Network (EVPN) Media Access Control (MAC) / IP Advertisement route and carries information relevant to the Address Resolution Protocol (ARP) / Neighbor Discovery (ND) resolution so that an EVPN Provider Edge (PE) implementing a proxy-ARP/ND function in broadcast domains (BDs) or an ARP/ND function on Integrated Routing and Bridging (IRB) interfaces can reply to ARP Requests or Neighbor Solicitation (NS) messages with the correct information.
