If configuring the Niagara station while installing BACnet/IP devices for a new BACnet/IP network, there are probably no existing BBMDs. In this case, you would typically follow Configure As BBMD. However, you would skip the step to specify a remote BBMD, unless one existed.

This would allow BACnet/IP devices on remote subnets to register with the station as foreign devices. You would not see other BBMDs in the Broadcast Distribution Table, but you could see if other devices have registered as foreign devices, in the Foreign Device Table.

See Foreign Device Table notes for related details.
