routing protocols : Benefits of link state routing and Drawbacks of link state routing

Link state routing protocols offer faster convergence and robustness by knowing the full network topology, making them less prone to routing loops. They are scalable and suitable for large networks, unlike distance vector protocols like RIP. However, they require more resources and complex configurations. Despite these drawbacks, their advantages make them preferable in large environments.
