Embedding the Rendezvous Point Address in an IPv6 Multicast Address
RFC 3956, “Embedding the Rendezvous Point Address in an IPv6 Multicast Address”, is a Proposed Standard document published in November 2004 by P. Savola, B. Haberman. It updates RFC 3306. It has since been updated by RFC 7371. The canonical text is published by the RFC Editor.
Abstract
This memo defines an address allocation policy in which the address of the Rendezvous Point (RP) is encoded in an IPv6 multicast group address. For Protocol Independent Multicast - Sparse Mode (PIM-SM), this can be seen as a specification of a group-to-RP mapping mechanism. This allows an easy deployment of scalable inter-domain multicast and simplifies the intra-domain multicast configuration as well. This memo updates the addressing format presented in RFC 3306. [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.
