RRAS Multicast Scope Configuration

Applies To: Windows Server 2008 R2

A multicast scope is a named range of IP multicast addresses that is expressed with an IP address and mask. After multicast scopes are configured, you can use them to create scope-based multicast boundaries in the properties of an IP routing interface.

Routing and Remote Access can forward multicast traffic in limited network configurations. The primary use of Routing and Remote Access as a multicast router is to connect a subnet to a multicast-enabled intranet that contains routers running multicast routing protocols. To fully support efficient multicast forwarding on a multiple-router intranet, you must install multicast routers that run one or more multicast routing protocols.

Events

Event ID Source Message

20157

RemoteAccess

The interface: %1 could not be enabled for multicast. %2 will not be activated over this interface.

20172

RemoteAccess

Multicast scope mismatch with %1: Locally-configured name: ""%2"", Remotely-configured name: ""%3"".

20173

RemoteAccess

Multicast scope address mismatch for scope ""%1"", Locally-configured range is: %4-%5, Remotely-configured range is: %2-%3

20174

RemoteAccess

Possible leaky multicast local scope detected between this machine and: %1, since a boundary appears to exist for: %2, but not for the local scope. If this warning continues to occur, a problem likely exists.

20175

RemoteAccess

Multicast scope: %1 is non-convex (the shortest path between two nodes within the zone passes outside the zone) since border router: %2 appears to be outside.

20176

RemoteAccess

A leak was detected in multicast scope: %1. One of the following routers is configured incorrectly: %2
