The command show running-config is used to view the active configuration in NVRAM to verify that the static route was entered correctly. The show ip route command is used to make sure that the static route is present in the routing table. Use the following steps to verify static route configuration Step 1 In privileged mode enter the command show running-config to view the active configuration. Step 2 Verify that the static route has been entered correctly. If the route is not correct it will be necessary to go back into global configuration mode to remove the incorrect static route and enter the correct one. Step 3 Enter the command show ip route. Step 4 Verify that the route that was configured is in the routing table. Troubleshooting Static Route Configuration Having knowledge of troubleshooting tools and procedures is just as important in static routing as in any other aspect of networking. You can use the show interfaces command to check the state and configuration of the interface that is to be used for the route gateway. Using the ping command helps you to determine whether end-to-end connectivity exists. If an echo reply is not received after a ping you can use the traceroute command to determine which router in the route path is dropping the packets. The routing process must happen on each router the packet travels through or the packet will be dropped. In many cases packets actually reach their destination but the remote network router has no knowledge of a route to reply to the sender. Use the following steps to troubleshoot a .
