2.2.1.2.37 MIB_IPMCAST_BOUNDARY

The MIB_IPMCAST_BOUNDARY structure contains a router's scoped IPv4 multicast address boundaries. This structure is used in the following methods:

• MIB_OPAQUE_INFO (section 2.2.1.2.52)

• MIB_IPMCAST_BOUNDARY_TABLE (section 2.2.1.2.38)

   typedef struct {
     DWORD dwIfIndex;
     DWORD dwGroupAddress;
     DWORD dwGroupMask;
     DWORD dwStatus;
   } MIB_IPMCAST_BOUNDARY,
    *PMIB_IPMCAST_BOUNDARY;
  

dwIfIndex: The index value for the interface that applies to this boundary. Packets with a destination address in the associated address/mask range are not forwarded with this interface.

dwGroupAddress: The 32-bit integer representation of the IPv4 group address which, when combined with the corresponding value in dwGroupMask, identifies the group range for which the scoped boundary exists.

Note Scoped addresses MUST come from the range 239.*.*.* as specified in [RFC2365].

dwGroupMask: The 32-bit integer representation of the IPv4 group address mask which, when combined with the corresponding value in dwGroupAddress, identifies the group range for which the scoped boundary exists.

dwStatus: A status value that describes the current status of this entry in a multicast forwarding entry (MFE) boundary table.

Value	Meaning
ROWSTATUS_ACTIVE 0x00000001	The entry has an active status.
ROWSTATUS_NOTINSERVICE 0x00000002	The entry has a notInService status.
ROWSTATUS_NOTREADY 0x00000003	The entry has a notReady status.
ROWSTATUS_CREATEANDGO 0x00000004	The entry has a createAndGo status.
ROWSTATUS_CREATEANDWAIT 0x00000005	The entry has a createAndWait status.
ROWSTATUS_DESTROY 0x00000006	The entry has a destroy status.
