Improve network reliability
4.1 STP (Spanning Tree Protocol)
Overview
Blocks a certain ports and there is only one active path for each network segment.
It’s a loop avoidance mechanism, a protocol used to solve problems that are
caused redundant topology like broadcast storm, multiple frame transmission &
MAC database instability.

Note: In the scenario both switch are configured with STP features. Assume switch
1 is the root bridge and the switch 2 port 5 is the blocked port. STP can’t prevent a
broadcast storm to happen and provide redundancy for a loop topology.
