When your networks evolve dynamically, routing protocols (BGP and OSPF) automatically get complicated in terms of updating optimal traffic path based on the state of network devices and routing configuration. But, it can also create problems such as hardware failures and misconfigurations which can be increasingly difficult for network administrators to manage. Dealing with issues like loss of connectivity or slow network can be avoided if admins can find out the root causes like route flapping, configurations errors or missing routes in routing table soon enough before it affects the users.
Manual troubleshooting can be tough!
Experienced network professionals would vouch that the best way to troubleshoot a network routing issue is to use the OSI Model and go layer-by-layer. You can refer to this detailed whitepaper and read more about the difference between manually troubleshooting routing issues and automating route monitoring. More importantly, you would need a tool that has intelligence to analyze and monitor network routes and changes to those routes.
How-to troubleshoot network routing issues
Do you want your network to function properly? Then routing should be the key focus create efficient network management. It is very important that you find the root cause of the routing issue and bring your network back on track.
Some of the common routing issues faced by network admins are:
The following slideshare will help you understand network route troubleshooting in 7 easy steps.
As you’ll see, the resources available in network management system will provide you with all the routing details. With a quick glance you will know everything about your routing data. If you combine real-time network routing information with network performance data and statistics, you can easily monitor all the changes in default routes, routing tables, BGP transitions and flapping routes. This will make your network troubleshooting much easier than manual processes.
