In computer networking, what is the key conceptual difference between link-state routing and distance-vector routing?
- 1Distance-vector routing algorithms have a lower probability of routing loops compared to link-state routing algorithms.
- 2Link-state routing requires every router to maintain a complete map of the entire network topology, whereas distance-vector routing requires routers to exchange vectors with direct neighbors only.✓
- 3Distance-vector routing algorithms are typically used in large-scale networks, while link-state routing algorithms are preferred in smaller networks.
- 4Link-state routing algorithms use path-vector protocols, while distance-vector routing algorithms use metrics such as hop count.
Correct answer
Link-state routing requires every router to maintain a complete map of the entire network topology, whereas distance-vector routing requires routers to exchange vectors with direct neighbors only.
