    S5900-24S4T2Q SWITCH MULTICAST CONFIGURATION 1. Multicast Overview The chapter describes how to configure the multicast routing protocol. For the details of the multicast routing commands, refer to the part "Multicast Routing Commands". The traditional IP transmission allows only one host to communicate with a single host (unicast communication) or to communicate with all hosts (broadcast communication).

    S5900-24S4T2Q SWITCH MULTICAST CONFIGURATION 3. IGMP Configuration 3.1 Overview a. IGMP Internet Group Management Protocol (IGMP) is a protocol used to manage multicast group members. IGMP is an asymmetric protocol, containing the host side and the switch side. At the host side, the IGMP protocol regulates how the host, the multicast group member, reports the multicast group it belongs to and how the host responds to the query message from the switch.

    S5900-24S4T2Q SWITCH MULTICAST CONFIGURATION Run the following command in interface configuration mode to modify the IGMP query interval on a port: Command Purpose Modifies the IGMP query interval on the current interface (unit: ip igmp query-interval time second). 3.2.3 Configuring IGMP Querier Interval As to version 2 and version 3 of the IGMP-Router protocol, if another switch that runs the IGMP-Router protocol exists in the same network, you need to choose a querier.

    S5900-24S4T2Q SWITCH MULTICAST CONFIGURATION Command Purpose Configures the IGMP query interval of the last group member ip igmp last-member-query-interval time (unit: ms). The previous command is useless for IGMP-RouterV1. 3.2.6 Configuring IGMP Query Interval for the Last Group Member Besides the functions regulated by the IGMP-Router protocol, BODCOM's switches support the static multicast group configuration on the port.

    S5900-24S4T2Q SWITCH MULTICAST CONFIGURATION 3.3 IGMP Characteristic Configuration Example All configurations about the IGMP characteristics are performed in VLAN port. Example for changing the IGMP version The IGMP-Router protocol of latter version is compatible with the IGMP host of low version, but cannot be compatible with the IGMP- Router protocol of the earlier version.
  • Page 15 S5900-24S4T2Q SWITCH MULTICAST CONFIGURATION The previous configuration command configures the static multicast group 224.1.1.7 on the interface ethernet 0/0, and defines source- filter of the multicast group as 192.168.20.168. That is, the interface belongs to the multicast group 224.1.1.7, but it only receives the IP multicast messages from 192.168.20.168.

    S5900-24S4T2Q SWITCH MULTICAST CONFIGURATION 4. Basic Multicast Routing Configuration 4.1 PIM-DM Introduction Protocol Independent Multicast Dense Mode (PIM-DM) is a multicast routing protocol in dense mode. By default, when the multicast source starts to send the multicast data, all network nodes in the domain receive the data. Therefore, PIM-DM forwards the multicast packets in broadcast-pruning mode.

    S5900-24S4T2Q SWITCH MULTICAST CONFIGURATION 4.2.2 Configuring State-Refresh The state-refresh control information of the PIM-DM is forwarded in management mode by default. The configuration commands in interface configuration mode are effective only to the configurations at the upstream ports when the first-hop switch directly connecting the source sends the state-refresh message periodically.
