Internet Group Management Protocol
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.
