The AT-GS950/16PS switch determines regional boundaries by examining the MSTP BPDUs received on the ports. A port that receives a MSTP BPDU from another bridge with regional information different from its own is considered to be a boundary port and the bridge connected to the port as belonging to another region.

The same is true for any ports connected to bridges running the single- instance spanning tree STP. Those ports are also considered as part of another region.
