Case Project 10-2 The network shown in Figure 10-21 consists of five class C networks con- nected via six routers. Each network has a single machine on it.

Several bus segments are con- nected using a partial-mesh topology 1. How many hops are there from one node to another? Make up a detailed table. What are all the IP addresses?Assign IPs for each machine and all router ports. Some IP addresses arc already suggested. Estimate how long it takes (assuming all routers come on line at the same time with their port-0 and port-1 IP addresses set) for the routing tables to tabilize. Use a 30-second RIP interval in your calculations. 3. 4. What entries are in router Ra's routing table: 5. If router Rf goes down, how does machine 4 talk to machine 5? 6. What is the minimum number of routers required to connect all five networks? 7. What is the impact of eliminating one router from the network in Figure 10-21? 8. What is the impact of eliminating two routers? Case Project 10-2 The network shown in Figure 10-21 consists of five class C networks con- nected via six routers.
