RRAS IGMP Multicast Group Joining

  • Article

Applies To: Windows Server 2008

Internet Group Management Protocol (IGMP) maintains host group membership on a local subnet. Hosts use IGMP to communicate multicast group membership requests with their local multicast router. Routers receive the group membership requests and periodically send queries to determine which host groups are active or inactive on the local subnet. This protocol is required to support Level 2 multicasting. Internet Protocol version 6 (IPv6) uses Multicast Listener Discovery (MLD) instead of IGMP to manage group membership.
