1.10 MSTP Configuration Example
I. Network requirements
Implement MSTP in the network shown in Figure 1-7 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.
