Ideally, a single routing protocol is used to exchange routing information in an enterprise network. However, organizational requirements such as partnerships, mergers, technology migrations, and changes in policy can make it necessary to support the use of multiple routing protocols in the same enterprise network. In such situations, route redistribution between the different routing protocols is often necessary to achieve IP connectivity between the different parts of the network, and this adds an extra layer of complexity to a routed network.
Enterprise networks may make use of the Border Gateway Protocol (BGP) to exchange routing information in a controlled fashion with external parties such as Internet service providers or other providers of IP-based services. The exterior gateway protocol BGP is often used in combination with an interior gateway protocol such as Enhanced Interior Gateway Routing Protocol (EIGRP) or the Open Shortest Path First (OSPF) routing protocol. And performance problems on network devices can cause degraded application performance and connectivity issues resulting in problems at the business level. Employees are not as productive as they could be or they might not be able to service their customers correctly. Understanding the mechanics of BGP and its interaction with interior gateway, and diagnosing and resolving router performance problems are therefore important skills for any network support engineer.
This course reviews the data structures and processes that play a part in the exchange of routing information between different routing protocols. The data structures used by BGP and the flow of routing information between routers running the BGP protocol, as well as the processing of routing information inside the router are detailed. The use of Cisco IOS commands to gather information about the operation of a route redistribution process, and the BGP data structures and routing processes is discussed, and the common causes for performance problems on routers such as high CPU utilization and memory allocation problems, as well as the typical solutions are also covered.


Troubleshooting Route Redistribution

  • identify the data structures and processes involved in route redistribution
  • verify the correct operation of a route redistribution process

  • verify the data structures that play a role in redistribution processes

Troubleshooting BGP

  • identify and resolve problems related to the exchange of routing information using BGP
  • resolve problems related to BGP
  • use Cisco IOS show commands to diagnose and resolve BGP routing problems

Troubleshooting Performance Problems on Routers

  • determine the root cause of high CPU usage on a router
  • use Cisco IOS commands to analyze packet forwarding through a router
  • identify typical symptoms and common causes of router performance problems
