Summary
This chapter covers the fundamentals of designing the various types of OSPF areas. The discussion began by looking at the issues surrounding the scalability and topology of OSPF, with a focus on the factors that you need to consider when designing a network. You then learned about the general items to consider that are common to designing all areas.
The “golden rules of design” were provided for all the essential portions of an OSPF network. Included within those discussions were the ability of OSPF to summarize routes and the benefits of using such a strong feature of the protocol.
