tailieunhanh - Designing & Implementing an OSPF Network

This chapter covers the actual process of sitting down and designing your OSPF network. The real process of putting the pen to paper and the true process behind it is covered. It is this chapter's intention to take the mystery out of designing any type of network. The concepts and steps discussed have universal application whether your network is BGP or OSPF; of course, the latter is emphasized. Chapter 6, "Advanced OSPF Design Concepts," covered many of the commands necessary for configuring OSPF. In this chapter, you will become familiar with the necessary steps to actually begin the OSPF process on a Cisco router.
