Explanation:
Dijkstra's Algorithm:
- OSPF (Open Shortest Path First) uses Dijkstra's algorithm to compute the shortest path.
- Dijkstra's algorithm is a graph search algorithm that solves the single-source shortest path problem for a graph with non-negative edge weights.
- It starts at the source node and explores the neighboring nodes to find the shortest path to all other nodes in the graph.
Bellman-Ford Algorithm:
- The Bellman-Ford algorithm is another algorithm used for finding the shortest path in a network.
- It can handle graphs with negative edge weights but is not typically used in OSPF.
Routing Information Protocol (RIP):
- RIP is another routing protocol that uses distance vector routing, which is different from OSPF.
- It does not use Dijkstra's algorithm for computing the shortest path.
Distance Vector Routing:
- Distance vector routing, used by protocols like RIP, determines the best path based on the number of hops to a destination.
- OSPF, on the other hand, uses Dijkstra's algorithm which considers the actual cost or weight of the paths.
In conclusion, OSPF uses Dijkstra's algorithm for computing the shortest path because it is efficient and suitable for networks with non-negative edge weights.
