Cisco ROUTE 2.0: Establishing OSPF Neighbor Relationships

OSPF is a link-state protocol based on the open standard. At a high level, OSPF operation consists of three main elements: neighbor discovery, link-state information exchange, and best-path calculation. To calculate the best path, OSPF utilizes SPF or Dijkstra's algorithm. The input information for the SPF calculation is link state information, which is exchanged between routers through several different OSPF message types. These message types help improve convergence and scalability in multiarea OSPF deployments. OSPF also supports several different network types, which enables you to configure OSPF over a variety of different underlying network technologies. After completing this course, you will be able to configure basic OSPF.
