ICND2 2.0: An Overview of OSPF

Anyone wishing to obtain Cisco Certified Network Associate (CCNA) 200-120 certification that validates the knowledge and skills required to install, operate, and troubleshoot a medium-sized network, including connecting to a WAN and implementing network security. Interconnecting Cisco Network Devices Part 2 (200-101 ICND2) is an essential course for students preparing for the CCNA Routing and Switching certification or the ICND2 certification. Students pursuing the CCNA Routing and Switching certification should attend parts 1 & 2 of the ICND course.Network administrators, network engineers, network managers, network designers, and project managers. Familiarity with network fundamentals, implementing local-area networks, Internet connectivity, managing network device security, implementing WAN connectivity and basic IPv6 connectivity is recommended.

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.


OSPF Overview

  • recognize advantages of link-state routing protocols over distance vector routing protocols
  • apply the OSPF metric to compare two paths
  • identify information contained in a hello packet
  • match update packets used to build and synchronize link-state databases with their definitions
  • define different neighbor states that OSPF routers go through
  • describe characteristics of the different kinds of routers in an OSPF area structure
  • match LSA types used in OSPF designs with their descriptions
