Configuration procedure
1) 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 trunk ports and assign them to related VLANs. The detailed
configuration procedure is omitted.
2) 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.
