Supported IP Multicast Protocol Standards

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

• RFC 1112, Host Extensions for IP Multicasting (defines IGMP Version 1)
• RFC 2236, Internet Group Management Protocol, Version 2
• RFC 2327, SDP: Session Description Protocol
• RFC 2710, Multicast Listener Discovery (MLD) for IPv6
• RFC 2858, Multiprotocol Extensions for BGP-4
• RFC 3031, Multiprotocol Label Switching Architecture
• RFC 3376, Internet Group Management Protocol, Version 3

  Only SSM include mode is supported.

• RFC 3590, Source Address Selection for the Multicast Listener Discovery (MLD) Protocol

  Only SSM include mode is supported.

• RFC 4601, Protocol Independent Multicast – Sparse Mode (PIM-SM): Protocol Specification (Revised)
• RFC 4607, Source-Specific Multicast for IP
• Internet draft draft-holbrook-idmr-igmpv3-ssm-07.txt, Using IGMPv3 and MLDv2 for Source-Specific Multicast (expires December 2004)
• Internet draft draft-ietf-l3vpn-2547bis-mcast-02.txt, Multicast in MPLS/BGP IP VPNs

  The scoping mechanism is not supported.

• Internet draft draft-raggarwa-l3vpn-2547-mvpn-00.txt, Base Specification for Multicast in BGP/MPLS VPNs (expires December 2004)

The following RFCs and Internet drafts do not define standards, but provide information about multicast protocols and related technologies. The IETF classifies them variously as “Best Current Practice,” “Experimental,” or “Informational.”

• RFC 1075, Distance Vector Multicast Routing Protocol

• RFC 3208, PGM Reliable Transport Protocol Specification
• RFC 3446, Anycast Rendevous [sic] Point (RP) mechanism using Protocol Independent Multicast (PIM) and Multicast Source Discovery Protocol (MSDP)
• RFC 3569, An Overview of Source-Specific Multicast (SSM)
• RFC 3618, Multicast Source Discovery Protocol (MSDP)
• RFC 3810, Multicast Listener Discovery Version 2 (MLDv2) for IPv6
• RFC 3973, Protocol Independent Multicast – Dense Mode (PIM-DM): Protocol Specification (Revised)
