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 unstable MAC address entries
on network devices.
Figure 14-15 Typical STP application
In Figure 14-15, STP is deployed
on the devices. The devices exchange information to discover loops
on the network and block ports. This ensures a loop-free tree network
and that the packet processing capabilities of switches is not impacted.
