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.
