Understanding OSPF Protocol

What type of routing protocol is OSPF?

• Link-state routing protocol

• Distance-vector routing protocol

• Hybrid routing protocol

• Path-vector routing protocol

How does OSPF differ from distance-vector protocols?

• OSPF is a link-state protocol, while distance-vector protocols share routing information based on neighbors.

• OSPF requires less memory and processing power than distance-vector protocols.

• Distance-vector protocols are more scalable than OSPF.

• OSPF uses a distance-vector algorithm to determine the best path.

What does LSA stand for in OSPF?

• Link State Analysis

• Link State Advertisement

• Local State Advertisement

• Link State Algorithm

What information is contained in an LSA?

• Statistics on internet traffic and usage patterns.

• Information about the state of a router's links, including link costs and statuses.

• Details on the physical location of routers.

• Information about the history of network protocols.

What algorithm do OSPF routers use to determine the best path?

• Dijkstra's algorithm (Shortest Path First)

• Floyd-Warshall algorithm

• A* search algorithm

• Bellman-Ford algorithm

In which type of network is OSPF primarily used?

• IP networks

• Bluetooth networks

• Token Ring networks

• Ethernet networks

What is the main advantage of link-state routing?

• Slower convergence due to partial network knowledge.

• Increased complexity in routing decisions.

• Higher bandwidth usage for routing updates.

• Faster convergence and more efficient routing due to complete network topology knowledge.

How do OSPF routers share information about their links?

• OSPF routers share information through Link State Advertisements (LSAs).

• OSPF routers share information via Routing Information Protocol (RIP).

• OSPF routers use Distance Vector updates.

• OSPF routers communicate through Network Address Translation (NAT).

What is the purpose of Dijkstra’s Algorithm in OSPF?

• To manage network congestion in OSPF.

• To establish a secure connection in OSPF.

• To calculate the shortest path for routing in OSPF.

• To encrypt data packets in OSPF.

Can OSPF operate across multiple autonomous systems?

• Yes, OSPF can operate across multiple autonomous systems.

• OSPF can be configured to work with BGP across autonomous systems.

• OSPF is designed specifically for inter-autonomous system routing.

• No, OSPF cannot operate across multiple autonomous systems.
