Abstract

The Internet Group Management Protocol Version 3 (IGMPv3) and theMulticast Listener Discovery Protocol Version 2 (MLDv2) are protocolsthat allow a host to inform its neighboring routers of its desire toreceive IPv4 and IPv6 multicast transmissions, respectively.Source-specific multicast (SSM) is a form of multicast in which areceiver is required to specify both the network-layer address of thesource and the multicast destination address in order to receive themulticast 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 andhosts to accommodate source-specific multicast. This document updatesthe IGMPv3 and MLDv2 specifications. [STANDARDS-TRACK]
