MIB_IPMCAST_BOUNDARY structure

The MIB_IPMCAST_BOUNDARY structure contains a row in a MIB_IPMCAST_BOUNDARY_TABLE structure that lists a router's scoped IPv4 multicast address boundaries.

Syntax


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

dwIfIndex

Type: DWORD

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

Note  Scoped addresses must come from the range 239.*.*.* as specified in RFC 2365.

dwGroupMask

Type: DWORD

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
