BACnetStack_ResetBroadcastDistributionTable

bool BACnetStack_ResetBroadcastDistributionTable();

Clears the router’s broadcast distribution table.

If the device is currently operating as a BBMD, it will be reset back to a plain device; BACnetStack_SetBBMD() must be called again to resume BBMD functionality. With more than one BACnet/IP Network Port, the table of every BACnet/IP data link is cleared and every one of them stops operating as a BBMD.

Note

Requires the STACK_OPTION_NM_BBMDC (with STACK_OPTION_DATA_LINK_LAYER_IPV4 and STACK_OPTION_OBJECT_TYPE_NETWORK_PORT) build option (it turns on STACK_OPTION_BVLL_BBMD, the macro this function checks).

BACnet reference: ANSI/ASHRAE 135-2024 Annex J: J.4.3.2 (Broadcast Distribution Table format).

Returns

True if successfully cleared, otherwise false.

Topic: BACnet/IP: BBMD and foreign devices. Declared in CASBACnetStackDLL.h.
