Why is STP protocol used?

The protocol achieves this by creating a logical tree structure within the physical network. It identifies all possible paths between nodes and eliminates redundant or unnecessary ones, ensuring that each node is connected via the most efficient route.

STP operates by continuously monitoring the network for changes and adjusting the spanning tree accordingly. Whenever a change occurs, such as the addition or removal of a device, STP recalculates the spanning tree to ensure that the network remains loop-free.

One of the key benefits of STP is its ability to maintain network reliability. By eliminating loops, STP helps prevent network outages caused by broadcast storms or other related issues. Additionally, it simplifies network management, as administrators no longer need to manually configure complex routing schemes to prevent loops.

STP, or Spanning Tree Protocol, is a fundamental Layer 2 network protocol designed to maintain the integrity of a network topology. Its primary function is to prevent the occurrence of loops, which can lead to numerous issues within a network.

Loops are problematic because they can cause broadcast storms, where data packets are endlessly circulated within the network, consuming bandwidth and ultimately leading to network congestion or even failure. STP ensures that only a single path exists between any two nodes, eliminating the risk of loops.
