Information technology

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?
