Figure 91 illustrates the concept of regions. It shows one MSTP region
consisting of two AT-9400 Series switches. Each switch in the region has
the same configuration name and revision level. The switches also have
the same five VLANs and the VLANs are associated with the same MSTIs.
Figure 91. Multiple Spanning Tree Region
The AT-9400 Series 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.
