Cisco TSHOOT 1.0: Network Layer Connectivity, OSPF, and EIGRP

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

Overview

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. Enhanced Interior Gateway Routing Protocol (EIGRP) and the Open Shortest Path First (OSPF) protocol are routing protocols that are commonly used in large enterprise networks. Troubleshooting problems related to the exchange of routing information is an essential skill for any network engineer who is involved in the implementation and maintenance of large routed enterprise networks that use EIGRP or OSPF as the interior gateway protocol (IGP).
This course provides the essential skills and knowledge needed to resolve network layer problems successfully. This includes coverage of the processes and data structures used by routers to forward IP packets, and the Cisco IOS tools available to diagnose problems related to IP packet forwarding. The data structures used by both EIGRP and OSPF, the flow of routing information between routers running EIGRP and OSPF, as well as the processing of routing information inside the router are detailed. In addition, the Cisco IOS commands that you can use to gather information from the EIGRP and OSPF data structures and routing processes are reviewed and individual case studies are presented to illustrate the use of the commands as part of a structured troubleshooting process.
