2.2.1.2.24 MIB_BOUNDARYROW

The MIB_BOUNDARYROW structure contains the IPv4 group address value and mask for a multicast boundary. Whenever this structure is used, the InfoType of RTR_TOC_ENTRY (section 2.2.1.2.4) MUST be 0xFFFF000B to specify multicast boundary information.

This structure is used in MIB_OPAQUE_INFO (section 2.2.1.2.52) structure.

This structure is used in the following methods:

• RRouterInterfaceTransportAdd (section 3.1.4.18)

• RRouterInterfaceTransportSetInfo (section 3.1.4.20)

• RRouterInterfaceTransportGetInfo (section 3.1.4.19)

   typedef struct {
     DWORD dwGroupAddress;
     DWORD dwGroupMask;
   } MIB_BOUNDARYROW,
    *PMIB_BOUNDARYROW;
  

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.
