MSTP configuration example
Network requirements
As shown in Figure 153 , to enable packets of different VLANs to be forwarded along different MSTIs,
perform the following configurations:
• 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, and the root bridge of MSTI 3 is Switch C.
