The BdtManager (Broadcast Distribution Table, or BDT) is the default view of the BroadcastDistributionTable under the Link container of an IpPort (BacnetIpLinkLayer). When the station is operating as a BBMD, Niagara maintains this table listing all other participating BBMDs, including their IP address and broadcast distribution masks. If necessary, this view allows you to manually edit the BDT. For related details, see BACnet/IP and BBMDs.
