Description

OSPF is a link-state routing protocol that is often used in networks due to scalability, fast convergence, and multivendor environment support. Understanding OSPF operations and OSPF terms is therefore important for network engineers who would like to design, implement, and troubleshoot scalable networks. In this lesson, a quick overview of link-state routing protocols, OSPF data structures, and OSPF metrics is done before explaining the functions of OSPF and its packet types. The course describes how the link-state database is built using LSAs, explains OSPF areas as a structure that gives OSPF scalability, defines area terminology, and draws attention to important design limitations. The course also highlights the OSPF neighbor adjacency process.
