Title: Chapter 8: Single-Area OSPF
Course: RITA MC - CISCO II > Section: Course Outline and Objectives

Overview, Objectives and Outline

Open Shortest Path First (OSPF) is a link-state routing protocol that was developed as a replacement for the distance vector routing protocol, RIP. RIP was an acceptable routing protocol in the early days of networking and the Internet. However, RIP's reliance on hop count as the only metric for determining best route quickly became problematic. Using hop count does not scale well in larger networks with multiple paths of varying speeds. OSPF has significant advantages over RIP in that it offers faster convergence and scales to much larger network implementations.

OSPF is a classless routing protocol that uses the concept of areas for scalability. This chapter covers basic, single-area OSPF implementations and configurations.

Learning Objectives for Chapter 8

- Configure single-area OSPFv2 in a small, routed IPv4 network
- Explain how OSPF uses cost to determine best path
- Verify single-area OSPFv2 in a small, routed netowrk
- Compare the characteristics and operations of OSPFv2 to OSPFv3
- Configure single-area OSPFv3 in a small, routed network
- Verify single-area OSPFv3 in a small, routed network
