45. For the network given in Figure 3.52, give global distance-vector tables like those of Tables 3.12 and 3.15 when: (a) each node knows only the distances to its immediate neighbors. (b) each node has reported the information it had in the preceding step to its immediate neighbors. (c) step (b) happens a second time. 2 A B E 3 F N 3 FIGURE 3.52 Network for Exercise 45
