MSTP Configuration Example

Network requirements
Implement MSTP in the network shown in
forwarded along different MSTIs. The detailed configurations are as follows:
All switches in the network belong to the same MST region.
Packets of VLAN 10, VLAN 30, VLAN 40, and VLAN 20 are forwarded along MSTI 1, MSTI 3, MSTI
4, and MSTI 0 respectively.
In this network, Switch A and Switch B operate on the convergence layer; Switch C and Switch D
operate on the access layer. VLAN 10 and VLAN 30 are limited in the convergence layer and VLAN 40
is limited in the access layer. Switch A and Switch B are configured as the root bridges of MSTI 1 and
MSTI 3 respectively. Switch C is configured as the root bridge of MSTI 4.
