STP Application

Loops often occur on a complex network, because multiple physical links are often deployed between two devices to implement link redundancy. Loops may cause broadcast storms and damage MAC address entries on network devices.

Figure 11-13  Typical STP application

As shown in Figure 11-13, STP is deployed on the devices. The devices exchange information to discover loops on the network and block a port to trim the ring topology into a loop-free tree topology. The tree topology prevents infinite looping of packets on the network and ensures packet processing capabilities of the devices.
