Description

IP routing is the core technology deployed in all current enterprise networks and is used in all areas of the network. For most connectivity problems in IP networks, the network layer is the point where troubleshooting processes start. The Open Shortest Path First (OSPF) protocol is a routing protocol commonly used in large enterprise networks. Troubleshooting problems related to the exchange of routing information is an essential skill for any network engineer that is involved in the implementation and maintenance of large routed enterprise networks that use OSPF as the IGP. This course reviews the processes and data structures that are used by routers to forward IP packets and the Cisco IOS tools that can be used to diagnose problems related to IP packet forwarding, to provide you with the essential skills and knowledge that are necessary to resolve network layer problems successfully. In addition, the Cisco IOS commands that you can use to gather information as part of a structured troubleshooting process from OSPF routing processes are reviewed.
