Cisco ICND2 1.1: Single-Area OSPF Implementation

This course is included in our On-demand training solution.


Open Shortest Path First (OSPF) is a classless interior gateway protocol (IGP). It is used within larger autonomous system networks in preference to the legacy distance vector routing protocols. OSPF is designated by the Internet Engineering Task Force (IETF) as one of several IGPs. Because OSPF is a widely deployed standard protocol, knowledge of its configuration and maintenance is essential. This course describes the function of OSPF and explains how to configure a single-area OSPF network on a Cisco router.
Because it is a link-state routing protocol, Open Shortest Path First (OSPF) scales well with a growing network. But this scalability introduces complexity in design, configuration, and maintenance. This course also introduces some of the common issues surrounding an OSPF network and a flowchart approach to troubleshooting these issues.
