Chapter 1. Overview of IP Routing


This chapter focuses on the general design and operation of routing protocols for the Internet Protocol (IP). It also provides background information on the IP protocol, as well as insights into how IP packets are routed through a data communications network. The ensuing discussions span IP routing principles and packet-switching mechanisms available on IP routers. Obviously, this chapter has a broader charter than the intended focus of this book. IS-IS-focused coverage starts in Chapter 2, "Introduction to the IS-IS Routing Protocol." This chapter covers the following major topics:

  • IP routing and forwarding

  • Essentials of IP addressing

  • Classification of IP routing protocols

  • Unicast versus multicast routing

  • Cisco packet-switching mechanisms

  • Comments on IPv6

The elaborate coverage of general IP routing issues should help remove many misconceptions held by most readers. For other readers, the material provides an excellent refresher on IP routing principles.
