WebNov 25, 2024 · Therefore, we have two algorithms. BFS calculates the shortest paths in unweighted graphs. On the other hand, Dijkstra’s algorithm calculates the same thing in weighted graphs. 3. BFS Algorithm. When dealing with unweighted graphs, we always care about reducing the number of visited edges. WebTo create a layer-3 forwarding table based on the output of the Dijkstra algorithm, you need to consider the final cost and predecessor information for each node. The cost represents the total cost of the shortest path from the source node to the destination node, while the predecessor represents the previous node on the shortest path.

Dijkstar is an implementation of Dijkstra's single-source shortest-paths algorithm. If a destination node is given, the algorithm halts when that node is reached; otherwise it continues until paths from the source node to all other nodes are found.
