6.1.6Troubleshooting static route configuration

The show interfaces command can be used to check the state and configuration of the interface that will be used for the route gateway. The ping command is used to determine if end-to-end connectivity exists. If an echo reply is not received after a ping, the traceroute command will be used to determine which router in the route path is dropping the packets.
