Review
1. What does hierarchy provide in a well-designed network?
2. What is the primary tool used to bound the area affected by network changes?
3. How can you determine which links can be removed from a fully-meshed core network to decrease the number of links?
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?
){kind=link}
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.
){kind=link}
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.
