ccna2.. Router B: Networks 192.168.1.0 and 192.16820.. Router C: networks 192.168.2.0 and 192.168.3.0oAfter the initial routing table exchange, each router processes the updates received from its neighbors and adds the new information to its routing table as necessary. Figure 14.2 shows the contents of each router's routing table after the initial exchange.Figure 14.2 Convergence Example - After the First Routing UpdateThis process is described separately for each router, starting with Router A.1. Receive network 192.168.1.0 and 192.16820 from Router B, and add 1 to the hop count for each route.2. Compare the routes advertised by Router B with the routes already in its routing table. 3. 192.168.2.0 is not in the routing table, so it is added to the routing table. 4. ignore the 192.168.1.0 advertised by Router B because it has a hop count of 1, while in the routing table, it has a hop count of 0. Next, look at Router C. 1. receive network 192.168.1.0 and 192.168.2.0 from Router B, and add 1 to their hop counts.2. compare the route advertised by routerB advertised route with the routes already in the routing table. 3. Add 192.168.1.0 to the routing table because it is not in it. 4. ignore 192.168.2.0 advertised by Router B because it has a hop count of 1 and the corresponding entry in the routing table has a hop count of 0. Finally, Router B is introduced because its situation is more complicated: it receives routes advertised by both Router A and Router B.The steps for Router B are as follows. 1. Receive networks 10.0.0.0 and 192.168.1.0 from Router A and 192.168.2.0 and 192.168.3.0 from Router C. Add 1 to the hop count for each of them.
