Operational Aspects of Proxy ARP/ND in Ethernet Virtual Private Networks

Overview

RFC 9161, “Operational Aspects of Proxy ARP/ND in Ethernet Virtual Private Networks”, is a Proposed Standard document published in January 2022 by J. Rabadan, S. Sathappan, K. Nagaraj, G. Hankins, T. King. It updates RFC 7432. The canonical text is published by the RFC Editor.

Abstract

This document describes the Ethernet Virtual Private Network (EVPN) Proxy ARP/ND function augmented by the capability of the ARP/ND Extended Community. From that perspective, this document updates the EVPN specification to provide more comprehensive documentation of the operation of the Proxy ARP/ND function. The EVPN Proxy ARP/ND function and the ARP/ND Extended Community help operators of Internet Exchange Points, Data Centers, and other networks deal with IPv4 and IPv6 address resolution issues associated with large Broadcast Domains by reducing and even suppressing the flooding produced by address resolution in the EVPN network.
