2.6.12 Example for configuring STP

Networking requirements
As shown in Figure 2-14, Switch A, Switch B, and Switch C form a ring network, so the loop
must be eliminated in the situation of a physical link forming a ring. Enable STP on them,
configure the priority of Switch A to 0, and path cost from Switch B to Switch A to 10.
