RRAS IGMP Packet Discarding

Updated: November 29, 2007

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.

If the IGMP router is discarding packets, support for Level 2 multicasting might fail.
