9.8IGMP Configuration

The Internet Group Management Protocol (IGMP) manages the multicast groups on a LAN. IP hosts use IGMP to report their group membership to directly connected multicast switches. Switches executing a multicast routing protocol maintain forwarding tables to forward multicast datagrams. Switches use the IGMP to learn whether members of a group are present on their directly attached sub-nets. Hosts join multicast groups by sending IGMP report messages.

IGMP uses group addresses, which are Class D IP addresses. The high-order four bits of a Class D address are 1110. Therefore, host group addresses can be in the range 224.0.0.0 to 239.255.255.255.

The address 224.0.0.0 will not be assigned to any group. The address 224.0.0.1 is assigned to all systems on a sub- net. The address 224.0.0.2 is assigned to all switches on a sub-net.

Multicast switches elect a designated switch for the LAN (subnet). The designated switch is the one with the highest IP address. The switch is responsible for sending IGMP host-query messages to all hosts on the LAN. By default, the designated switch sends IGMP host-query messages every 60 seconds in order to keep the IGMP overhead on hosts and networks very low.
