Supported IP Multicast Protocol Standards

The JUNOS Software substantially supports the following standards for IP multicast protocols, including Protocol Independent Multicast (PIM), Distance Vector Multicast Routing Protocol (DVMRP), Internet Group Management Protocol (IGMP), Multicast Listener Discovery (MLD), Multicast Source Discovery Protocol (MSDP), Pragmatic General Multicast (PGM), Session Announcement Protocol (SAP), and Session Description Protocol (SDP).
