Link costs
To calculate path costs, switches add the costs of all the links in the path.
STP assigns each link a cost, based on its speed. The higher the port speed, the
lower the cost.
The following illustration shows the comparison of the cost of each path of the root
bridge.
Note
These are the root costs specified in the updated standard Rapid Reconfiguration
Spanning Tree Protocol (RSTP), which you will learn more about in Lesson 3.
