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.

This document is a product of the BGP Enabled Services Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
