Configure Switch C: Step Operation Description 1 Configure ports On VLAN→802.1Q VLAN page, configure the link type of the related ports as Trunk, and add the ports to VLAN 101-VLAN 106. The detailed instructions can be found in the section 802.1Q VLAN. 2 Enable STP function On Spanning Tree→STP Config→STP Config page, enable STP function and select MSTP version. On Spanning Tree→STP Config→Port Config page, enable MSTP function for the port. 3 Configure the region name and On Spanning Tree→MSTP Instance→Region Config the revision of MST region page, configure the region as PS-G and keep the default revision setting. 4 Configure VLAN-to-Instance On Spanning Tree→MSTP Instance→Instance mapping table of the MST region Config page, configure VLAN-to-Instance mapping table. Map VLAN 101, 103 and 105 to Instance 1; map VLAN 102, 104 and 106 to Instance 2. 5 Configure switch C as the root On Spanning Tree→MSTP Instance→Instance bridge of Instance 1 Config page, configure the priority of Instance 1 to be 4096. 6 Configure switch C as the root On Spanning Tree→MSTP Instance→Instance bridge of Instance 2 Config page, configure the priority of Instance 2 to be 0. Configure Switch D: Step Operation Description 1 Configure ports On VLAN→802.1Q VLAN page, configure the link type of the related ports as Trunk, and add the ports to VLAN 101-VLAN 106. The detailed instructions can be found in the section 802.1Q VLAN. 2 Enable STP function On Spanning Tree→STP Config→STP Config page, enable STP function and select MSTP version.
