Configuration procedure

1. Configure VLANs and VLAN member ports:

Create VLAN 10, VLAN 20, and VLAN 30 on Router A and Router B, respectively. Create VLAN

10, VLAN 20, and VLAN 40 on Router C, and VLAN 20, VLAN 30, and VLAN 40 on Router D.

Configure the ports on these devices as trunk ports and assign them to related VLANs. (Details not

shown.)

2. Configure Router A:

# Enter MST region view and configure the MST region name as example. Map VLAN 10, VLAN

30, and VLAN 40 to MSTI 1, MSTI 3, and MSTI 4, respectively. Configure the revision level of the

MST region as 0.

3. Configure Router B:

# Enter MST region view, and configure the MST region name as example. Map VLAN 10, VLAN

30, and VLAN 40 to MSTI 1, MSTI 3, and MSTI 4, respectively. Configure the revision level of the

MST region as 0.
