Operational Aspects of Proxy ARP/ND in Ethernet Virtual Private Networks
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
