Protocol Independent Multicast - Sparse Mode Multicast Routing Security Issues and Enhancements
RFC 4609, “Protocol Independent Multicast - Sparse Mode Multicast Routing Security Issues and Enhancements”, is an Informational document published in October 2006 by P. Savola, R. Lehtonen, D. Meyer. The canonical text is published by the RFC Editor.
Abstract
This memo describes security threats for the larger (intra-domain or inter-domain) multicast routing infrastructures. Only Protocol Independent Multicast - Sparse Mode (PIM-SM) is analyzed, in its three main operational modes: the traditional Any-Source Multicast (ASM) model, the source-specific multicast (SSM) model, and the ASM model enhanced by the Embedded Rendezvous Point (Embedded-RP) group-to-RP mapping mechanism. This memo also describes enhancements to the protocol operations that mitigate the identified threats. This memo provides information for the Internet community.
What “Informational” means
Published for the general information of the community. It does not define an IETF standard and carries no standards-track status.
