MSTP Configuration Example
Network requirements
Implement MSTP in the network shown in Figure 1-10 to enable packets of different VLANs to be
forwarded along different MSTIs. The detailed configurations are as follows:
z
All switches in the network belong to the same MST region.
z
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.

The word “permit” shown in Figure 1-10 means the corresponding link permits packets of specific
VLANs.
