You must see a BBMD as a tunnel between 2 BACnet networks, it takes a broadcast message from network 1 as unicast message and broadcast it on the secondary network again. Only ONE BBMD should be configured per TCP/IP subnet. I repeat ONLY ONE ! Just like KNX routers you can only have one tunnel between your 2 networks to avoid loops.
As you can see in this image you need a BBMD in each network, if you only have one BBMD you might want to register it as foreign device..
