7.5
Application Example for STP Function
Network Requirements
Switch A, B, C, D and E all support MSTP function.
A is the central switch.
B and C are switches in the convergence layer. D, E and F are switches in the access layer.
There are 6 VLANs labeled as VLAN101-VLAN106 in the network.
All switches run MSTP and belong to the same MST region.
The data in VLAN101, 103 and 105 are transmitted in the STP with B as the root bridge. The
data in VLAN102, 104 and 106 are transmitted in the STP with C as the root bridge.
