Employees are unable to connect to servers on one of the internal networks. What should be done or checked?
- Use the “show ip interface brief” command to see if an interface is down.
- Verify that there is not a default route in any of the edge router routing tables.
- Create static routes to all internal networks and a default route to the internet.
- Check the statistics on the default route for oversaturation.
Explanation: When connectivity to a specific internal network is lost, the network administrator must determine if the physical or logical path is active. The show ip interface brief command is a fundamental troubleshooting tool that provides a quick summary of the status and protocol for all interfaces, allowing the technician to immediately see if an interface has failed or been administratively shut down. While checking for oversaturation is useful for sporadic issues, a complete inability to connect typically requires verifying interface operational status first.
