Internet Group Management Protocol

CHAPTER 18

Internet Group Management Protocol (IGMP) is used by IPv4 Multicast routers to learn about the existence of host group members on their directly attached subnet (see RFC 2236). The IPv4 Multicast routers get this information by broadcasting IGMP Membership Queries and listening for IPv4 hosts reporting their host group memberships. This process is used to set up a client/server relationship between an IPv4 Multicast source that provides the data streams and the clients that want to receive the data.

The G8124 can perform IGMP Snooping, and connect to static multicast routers (Mrouters). The G8124 can act as a Querier, and participate in the IGMP Querier election process.

Note – BLADEOS 6.5 does not support IPv6 for IGMP.

The following topics are discussed in this chapter:
