Introduction to IGMP
Internet Group Management Protocol (IGMP) is used to register dynamic multicast group membership. It
can register a router to receive specific multicast traffic. IGMP traffic will only be sent to those team
members that are part of a multicast group.
When a server runs an application that wants to join a multicast group, the join message is sent out to the
aggregation and only those ports in the multicast group. During a failover situation, the NCU will
maintain connectivity with the multicast group and respond with IGMP reports.
The HP NCU supports IGMP in this release, but it does not require any user input in the NCU; therefore,
no windows and controls exist.
