A fragment of a network is shown below. The costs of the links between router A and its neighbors are shown in the figure. In this network, the distance vector routing algorithm with poisoned reverse is used by the routers to determine the distances to all destinations in the network. The latest distance vectors received by A just before the algorithm stabilizes are given below. The latest distance vectors received by node A: a. (10 pts) By using the latest distance vectors received by A, compute A's distance vector. b. (5 pts) According to the computation made in part (a), give the forwarding table in node "A" and indicate for each destination. c. (15 pts) After the algorithm stabilizes, the cost of link between A and B increases to 50 and A detects the change before B. What distance vectors does A send to each of its neighbors just after the link cost change
