What is a major benefit of using Link State Protocols over Distance Vector Protocols?

Slower convergence times

Lesser bandwidth requirements

Faster convergence times

One of the major benefits of using Link State Protocols is that they typically allow for faster convergence times compared to Distance Vector Protocols. Fast convergence is crucial in network environments because it reduces the time taken for routers to update their routing tables and reach a stable state after a change occurs, such as a link failure or a new route being added.

In Link State Protocols, each router constructs a complete map of the network by gathering information from all other routers' link states. This allows routers to independently calculate the best paths using algorithms like Dijkstra's Shortest Path First. The result is a quicker reaction to changes, leading to minimal disruption in network traffic and improved overall stability of the network.

In contrast, Distance Vector Protocols rely on each router sharing its routing table with directly connected neighbors, which can lead to slower convergence due to the time it takes for this information to propagate through the network and for routes to be recalculated. Thus, the inherent design of Link State Protocols provides a significant advantage in terms of speed during network changes.
