Multicast Router Discovery

Overview

RFC 4286, “Multicast Router Discovery”, is a Proposed Standard document published in December 2005 by B. Haberman, J. Martin. The canonical text is published by the RFC Editor.

Abstract

The concept of Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) snooping requires the ability to identify the location of multicast routers. Since snooping is not standardized, there are many mechanisms in use to identify the multicast routers. However, this can lead to interoperability issues between multicast routers and snooping switches from different vendors.

This document introduces a general mechanism that allows for the discovery of multicast routers. This new mechanism, Multicast Router Discovery (MRD), introduces a standardized means of identifying multicast routers without a dependency on particular multicast routing protocols. [STANDARDS-TRACK]

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.
