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.

What is one advantage of link state routing protocols over distance vector protocols?

• They require less memory.

• They converge faster.

• They are simpler to configure.

• They do not need a topology map.

How do link state routing protocols reduce the risk of routing loops?

• By ignoring topology changes.

• By using static routes only.

• By using a single routing table.

• By knowing the full network topology.

What is a benefit of the hierarchical design in link state routing protocols?

• It increases the size of routing tables.

• It simplifies the network design.

• It allows for address summarization.

• It eliminates the need for a backbone area.

Why do link state routing protocols require more memory?

• They store multiple tables.

• They rely on external memory sources.

• They do not use a topology database.

• They use a single routing table.

What is a strict design requirement for OSPF in link state routing protocols?

• No backbone area is needed.

• All areas must be isolated.

• No areas should connect to area 0.

• All areas must connect to area 0.
