Collection of BACnet BBMD Best Practices

• Watch out for “auto-correcting” BBMD “managers”. These well intentioned, automatic, procedures are often vendor specific, and may ensure that the BDT (BBMD Address Tables) are valid among a given group of devices from one vendor, they can often neglect to update the BBMD tables in devices from other vendors.
• Although the BACnet specification now allows multiple BBMDs per IP subnet, avoid this practice. Additional BBMDs means additional configuration checks over the years (decades) of future network management.
