• All devices on the network are in the same MST region. Device A and Device B work on the
distribution layer, while Device C and Device D work on the access layer.
• Configure MSTP so that packets of different VLANs are forwarded along different spanning trees:
Packets of VLAN 10 are forwarded along MSTI 1, those of VLAN 30 are forwarded along MSTI 3,
those of VLAN 40 are forwarded along MSTI 4, and those of VLAN 20 are forwarded along MSTI
0.
• VLAN 10 and VLAN 30 are terminated on the distribution layer devices, and VLAN 40 is
terminated on the access layer devices, so the root bridges of MSTI 1 and MSTI 3 are Device A and
Device B respectively, while the root bridge of MSTI 4 is Device C.

Configuration procedure
Step1 VLAN and VLAN member port configuration
Create VLAN 10, VLAN 20, and VLAN 30 on Device A and Device B respectively, create VLAN 10,
VLAN 20, and VLAN 40 on Device C, and create VLAN 20, VLAN 30, and VLAN 40 on Device D;
configure the ports on these devices as hybrid ports and assign them to related VLANs; configure the
security zones to which the combinations of these ports and their permitted VLANs belong. The detailed
configuration procedure is omitted.
Step2 Configuration on Device A
# Enter MST region view, configure the MST region name as example, map VLAN 10, VLAN 30, and
VLAN 40 to MSTI 1, MSTI 3, and MSTI 4 respectively, and configure the revision level of the MST region
as 0.
• Log in to Device A. Select Network > MSTP > Region from the navigation tree, click Modify,
and make the following configurations on the page shown in Figure 12 .
