In MSTP, the relationship between VLAN and STP is described through the MSTP configuration table. MSTP
configuration table, configuration name and configuration edit number makes up of the MST configuration
identifier.
In the network, interconnected bridges with same MST configuration identifier are considered in the same
MST region. Bridges in the same MST region always have the same VLAN configuration, ensuring VLAN
frames are sent in the MST region.
