Assume that the network in Figure 20.34 uses distance-vector routing with the forwarding table as shown for each node.

Figure 20.34

If each node periodically announces their vectors to the neighbor using the poison-reverse strategy, what is the distance vector advertised in the appropriate period:

a. From A to B?

b. From C to D?

c. From D to B?

d. From C to A?

A A B B C 8 D D 7B 4 A B D B 2 8 D B
