This video is explaining to the viewer what the spanning tree protocol is and what it used for in cyber
security. The Spanning Tree Protocol is very useful in situations where you have multiple switches with
redundant links. This is common in production switch networks and is done to provide fault tolerance.
One of the benefits of the Spanning Tree Protocol is that it provides fault tolerance by recognizing when
there are multiple paths through the network and controlling which paths are available by dynamically
blocking and unblocking switch ports and in the event that one of the switch ports was to fail.
With the Spanning Tree Protocol operating and using the spanning tree algorithm, the Spanning Tree
Protocol will find the redundant links and block one of the switch ports, which enables a single path to
the destination and thereby mitigates the possibility of a switching loop.
