Routing TCP[s]IP (Vol. 22001)

 

This chapter has explored both the motives for inventing an inter-AS routing protocol and the reasons why EGP has proven inadequate in that role. Chapter 2 introduces the protocol that has replaced EGP, the Border Gateway Protocol, and examines its operation. Table 1-10 summarizes the commands used in this chapter.
