MSTP Configuration Example

Network requirements
Configure MSTP in the network shown in
forwarded along different MSTIs. The detailed configurations are as follows:
All devices on the network are in the same MST region.
Packets of VLAN 10, VLAN 20, VLAN 30, and VLAN 40 are forwarded along MSTI 1, MSTI 2, MSTI
3, and MSTI 0 respectively.
Switch A and Switch B operate at the distribution layer; Switch C and Switch D operate at the
access layer. VLAN 10 and VLAN 20 are terminated on the distribution layer devices, and VLAN 30
is terminated on the access layer devices, so the root bridges of MSTI 1 and MSTI 2 are Switch A
and Switch B respectively, while the root bridge of MSTI 3 is Switch C.
Number of VLANs mapped to the current MSTI
Major parameters for the port:
Hello: Hello timer
MaxAge: Max Age timer
FWDly: Forward delay timer
MsgAge: Message Age timer
Remain Hop: Remaining hops
