Consider a network with the following topology: 6. D The owner of the network is deploying a distance-vector routing protocol and the distance vector protocol exchanges distance-vectors every R seconds and the routers send their distance-vector before processing distance-vectors received from other routers. After two rounds, the distance vector table at router F looks as follows: Link E-F F Dest. Cost 15 A E-F 12 E-F 12 E-F local 7 a) How does the distance vector table at router F look like after the next round? b) Will there be further changes after the third round? If yes, which ones? If not, why not? c) Is it possible that F knows a cost towards a certain destination that is lower than the cost known by E for the same destination? Explain. BCDEF
