routing protocols : Types of Routing Protocols -Distance Vector, Link State

The video tutorial explains two types of routing protocols: distance vector and link state. Distance vector protocols, like RIP, use hop count to determine the best path and rely on information from neighboring routers, which can lead to routing loops and instability. Mechanisms like split horizon and poison reverse help mitigate these issues. Link state protocols, such as OSPF, maintain a complete map of the network, allowing routers to make more informed decisions using the Shortest Path First algorithm. While link state protocols offer better visibility, they require more complex configurations and resources.

What is a key advantage of distance vector routing protocols?

• They use the Shortest Path First algorithm.

• They have a complete view of the network.

• They require a hierarchical network topology.

• They are easy to configure.

Which algorithm is used by distance vector routing protocols to calculate paths?

• Bellman-Ford algorithm

• Floyd-Warshall algorithm

• Dijkstra's algorithm

• Kruskal's algorithm

What is a common issue with distance vector routing protocols?

• They can be easily fooled by incorrect information.

• They require a lot of memory.

• They need a hierarchical network topology.

• They are difficult to configure.

Which feature is used to prevent routing loops in distance vector protocols?

• Link state database

• Shortest Path First

• Split horizon

• Hierarchical topology

How do link state routing protocols differ from distance vector protocols?

• They are simpler to configure.

• They have a complete map of the network.

• They use hop count as a metric.

• They rely on neighbor information.

What is the main routing metric used by OSPF?

• Packet loss

• Cost based on bandwidth

• Latency

• Hop count

What is a disadvantage of link state routing protocols?

• They need a hierarchical network topology.

• They require less memory.

• They have limited visibility.

• They are easy to configure.
