Figure 7-12 MSTI concepts
Each VLAN can map to one MSTI; that is to say, data of one VLAN can only be
transmitted in one MSTI while one MSTI may correspond to several VLAN.
Compared with the previous STP and RSTP, MSTP has obvious advantages, including
cognitive ability of VLAN, load balance sharing ability, similar RSTP port status switching
ability as well as binding multiple VLAN to one MST instance to reduce resource occupancy
rate. In addition, MSTP running devices in network are also compatible with the devices
running STP and RSTP.
