_______ is not one of the step in Link state routing algorithmQuestion 46Select one:a.Discover its neighbors and learn their network addressesb.Compute the shortest path to every other routerc.Set the distance or cost metric to each of its neighboursd.Both a and ce.All of these

You are given a state graph with link costs. The running time of the algorithm should be a function of the number of states in the graph and the algorithm should guarantee that the path with shortest path cost is found.            Choose the most efficient search method that meets the criteria indicated above.

5.2-2. Dijkstra’s link-state routing algorithm. Consider Dijkstra’s link-state routing algorithm that is computing a least-cost path from node a to other nodes b, c, d, e,  f.  Which of the following statements is true.  (Refer to Section 5.2 in the text for notation.)Group of answer choicesSuppose nodes b, c, and d are in the set N’.  These nodes will remain in N’ for the rest of the algorithm, since the least-cost paths from a to b, c, and d are known.The values computed in the vector D(v), the currently known least cost of a path from a to any node v, will always decrease following an iteration.Following the initialization step, if nodes b and c are directly connected to a, then the least cost path to b and c will never change from this initial cost.The values computed in the vector D(v), the currently known least cost of a path from a to any node v, will never increase following an iteration.In the initialization step, the initial cost from a to each of these destinations is initialized to either the cost of a link directly connecting a to a direct neighbor, or infinity otherwise.
