MRTM Command Descriptions

Unlike traditional Internet traffic that requires separate connections for each source-destination pair, IP Multicasting allows many recipients to share the same source. The IP Multicast protocol sends data to distributed servers on the multicast backbone, and MRTM allows different IP protocols to work together on the same router. This means that just one set of packets is transmitted for all destinations. MRTM also manages Multicast Open Shortest Path First (MOSPF), and provides multicast routing support for Resource Reservation Protocol (RSVP). For large amounts of data, IP Multicast is more efficient than normal Internet transmissions because the server can broadcast a message to many recipients simultaneously. This section contains an alphabetized list and descriptions of the MRTM IP multicast commands supported by the BSR.
