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.

For the definition of Status, see RFC 2026.

For the definition of Stream, see RFC 8729.
