What is a main advantage of using RSTP over STP?

RSTP, or Rapid Spanning Tree Protocol, offers a significant advantage over the original Spanning Tree Protocol (STP) primarily due to its ability to provide faster convergence upon topology changes. When there is a change in the network topology, such as a link failure or addition of a new switch, RSTP can quickly react and reconfigure the network to maintain loop-free topology.

This enhanced rapid convergence is achieved through the use of a more efficient mechanism for port states and roles. RSTP introduces additional port states, such as listening and learning, which streamline the transition process and reduce the time it takes for a switch to recognize changes in the network. Additionally, RSTP can utilize the practical concept of "edge ports," identifying ports that connect directly to end devices and shortening the convergence time even further.

In contrast, traditional STP might take up to 30 to 50 seconds to converge after a topology change, whereas RSTP can typically achieve convergence in mere seconds. This speed is crucial in modern networks where availability and performance are paramount, making RSTP a more robust solution for maintaining network stability during changes.
