This course examines the Open Shortest Path First (OSPF) routing protocol. It explains OSPF in comparison to the Routing Information Protocol (RIP), and covers discovery, selection, route maintenance, and point-to-point operation. The two formal modes of running OSPF over an NBMA topology are discussed, and OSPF configuration and verification are explained in detail.
Objectives:
After completing this course, students will be able to:
- Understand the differences between OSPF and RIP
- Explain how the Hello protocol works
- Describe the eight possible states that an OSPF router can go through during the initialization process
- Use IP unnumbered and loopback addressing
- Configure and verify different OSPF operations for a single area
