Configure IGMP features
Configure IGMP features to enable dynamic registration of individual hosts in multicast groups on a particular LAN and to manage multicast traffic efficiently.
IP hosts use IGMP to report their group memberships to directly-connected multicast routers. IGMP is used to dynamically register individual hosts in a multicast group on a particular LAN. Hosts identify group memberships by sending IGMP messages to their local multicast router. Under IGMP, routers listen to IGMP messages and periodically send out queries to discover which groups are active or inactive on a particular subnet.
