(b Given the network link in Figure Q2b where the link cost for each node is given in the diagram, (X is a number, using last digit from your student ID), answer the following question. By using distance-vector Bellman-Ford routing algorithm, complete the routing table for node a below: Router -1 b 6 3 1 -2 a C 5 -2 3 -1 f Figure Q2b [7 Marks] (ii) Why is the routing table not the same for all nodes using distance-vector routing?
