1. How many hops are there from one node to another? Make up a detailed
table.
2. What are all the IP addresses? Assign IPs for each machine and all router
ports. Some IP addresses are already suggested.
3. 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
stabilize. Use a 30-second RIP interval in your calculations.
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?
