Managing and Troubleshooting Static Routes
It is important to be able to properly manage and troubleshoot static routes. When a static route is no
longer needed, that static route should be deleted from the running and startup configuration files.
Troubleshooting a Missing Route
Troubleshooting is a skill that develops as you gain more experience. It is always best to look for the
most obvious and simplest issues first, such as an interface still in shutdown mode or an interface with
the wrong IP address. After these items have been verified, begin looking for more complicated possi-
bilities, like an error in the static route configuration.
List at least four commands that can help you troubleshoot a missing route.
