RRAS IGMP
Applies To: Windows Server 2008 R2
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.
Aspects
The following is a list of all aspects that are part of this managed entity:
| Name | Description |
|---|---|
The Routing and Remote Access service has determined that IGMP audits generated an audit entry when a system event was executed successfully. These events confirm successful IGMP operations. |
|
To support Internet Protocol version 4 (IPv4) multicast applications on a single-router intranet or when connecting a single-router intranet to the Internet, you can use the Routing and Remote Access service, add the IGMP routing protocol on each server, and configure the server's outbound interface for IGMP router mode and its inbound interface for IGMP proxy mode. If your multicast applications cross the Internet, the outbound interface is the intranet interface and the inbound interface is the Internet interface. |

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. IGMP must be enabled to support Level 2 multicasting. |

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.

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. |

To support Internet Protocol version 4 (IPv4) multicast applications on a single-router intranet or when connecting a single-router intranet to the Internet, you can use the Routing and Remote Access service, add the (Internet Group Management Protocol (IGMP) routing protocol on each server, and configure the server's outbound interface for IGMP router mode and its inbound interface for IGMP proxy mode. After IGMP is initialized on an interface, multicast group membership requests can be communicated. |

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. Socket operation for IGMP involves the configuration of the router to receive packets from the neighboring router.
