(2) Path between terminals on floor 2 and the server

- On the backbone (ring) network, you use the VLAN mapping that contains the VLANs used on floor 2 (VLANs

in the 200s) and configure the primary port of the ring for the path between devices C10 and C11.

- For STP on base 2 (floor 2), you adjust the bridge ID so that device F21 can be the root bridge.

(By default, devices F20 and F21 have a bridge priority of 0, and device F2 has a bridge priority of 32768.

So, by setting the bridge priority of device F20 to 4096, device F21 can be the root bridge.)

- For STP on base 10 (server), use PVST+ and adjust the bridge priority of the devices so that device C11 will be

the root bridge for the VLAN12, a VLAN for data communication with terminals on floor 2.

(By default, devices C10 and C11 have a bridge priority of 0, and device S1 has a bridge priority of 32768.

So, by setting the bridge priority of device C10 for VLAN12 to 4096, device C11 can be the root bridge.)

- Configure VRRP so that device C11 will be the master for the VLANs in the 200s and VLAN12.

With these settings, the communication path between terminals on floor 2 and the server is established as shown

in Figure 3.
