Using Internet Group Management Protocol Version 3 and Multicast Listener Discovery Protocol Version 2 for Source- Specific Multicast
RFC 4604, “Using Internet Group Management Protocol Version 3 and Multicast Listener Discovery Protocol Version 2 for Source- Specific Multicast”, is a Proposed Standard document published in August 2006 by H. Holbrook, B. Cain, B. Haberman. It updates RFC 3376, RFC 3810. The canonical text is published by the RFC Editor.
Abstract
The Internet Group Management Protocol Version 3 (IGMPv3) and the Multicast Listener Discovery Protocol Version 2 (MLDv2) are protocols that allow a host to inform its neighboring routers of its desire to receive IPv4 and IPv6 multicast transmissions, respectively. Source-specific multicast (SSM) is a form of multicast in which a receiver is required to specify both the network-layer address of the source and the multicast destination address in order to receive the multicast transmission. This document defines the notion of an "SSM-aware" router and host, and clarifies and (in some cases) modifies the behavior of IGMPv3 and MLDv2 on SSM-aware routers and hosts to accommodate source-specific multicast. This document updates the IGMPv3 and MLDv2 specifications. [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.
