5.2. Areas and Router Types
Throughout this chapter, I have pointed out topics that are discussed in more detail in the context of LS database synchronization in Chapter 6. With the completion of the discussion of flooding, we are almost there. But there are still three basics you need to know about before tackling synchronization: metric types, and the details of the OSPF LSAs and IS-IS TLVs used in the synchronization process. These three topics depend on some knowledge of OSPF and IS-IS router types, which are best understood in the context of areas. Chapter 7 discusses areas in depth, but the very basic concepts (beyond what was introduced in Chapter 2) are covered here for the purpose of defining router types.
