4. What provides ways around failure points in the network?

5. What two things are most desirable in a routing protocol?

6. What can a routing protocol do to decrease it's burden to hosts that are not running routing on a network?

7. List the addressing problems that are caused by having multiple links to external networks.

8. Given the network shown in Figure 4-10, how many routes do you think a core router will have in its table if no summarization is applied?

9. How many routes do you think a core router will have in its table if all possible summarization is done?

10. Define the core, distribution, and access layers of the network shown in Figure 4-11.

11. Correct any problems in the topology that will affect the stability of the network pictured in Figure 4-11. Explain the changes you make and why.

12. Address the network shown in Figure 4-11 in a way that reduces the routes in the core to a minimum.
