Figure 84 Each RIP node advertises the contents of its routing table to its immediate neighbors

nouWr 3

In Figure 8-4, there are four routers. The gateway router is interconnected with each of the other three. It must exchange its routing information with these routers. Routers A, B, and C have only one connection to the gateway. Consequently, they can only exchange their information with the gateway directly. They can learn about each other's hosts through the information shared with the gateway. Table 8-1 shows the abbreviated contents of each of the three routers' routing tables. This information is shared with the gateway router. For the sake of simplicity, this example uses fictitious and generic network addresses. This generic addressing is intended to help you understand the mechanics of routing without the complexity of IP addressing. Examples with IP addresses are presented later in this chapter, as well as throughout the remainder of the book.
