Cisco’s show IP route command will allow a router or switch to show the current subnet mask of a given network. The command, used in conjunction with the show interface command, will reveal the network’s internal IP addresses. In fact, one of the main reasons that routers are used is to hide the real IP addresses of the internal network from outsiders. The command lets you know the internal network’s IP address, allowing you to create aliases and enable forwarding.
To show the IP route, check the Status column on the Network panel and click on the option “inet work” tab. Then click on the option “ip route.” Look for the subnet mask of the internal network. You should be able to see the listed subjects, the subjects of which you can enter into the show ip route command. Enter the IP addresses of the internal network, one by one, into the text box.
When you view the status of the command, you should see a forwarding table appearing. You may need to scroll to the bottom of the window to get to the forwarding configuration. If you have a normal router, the table should be set up like this:

If you have a router for virtual private LANs (VPLS), then it shows a different route for each interface. The command for the show ip route will return with one or more subnets as the network’s IP addresses. In this case, VPLS routers must be manually inserted into the setup.
Another scenario for a show IP route scan is when you are investigating a strange device on your network. For example, if you discover that a wireless printer is connected to ten other devices, but the only other device has an IP address of 0.0.0.0, then this probably means that someone has hacked into your network and is attempting to use this printer as a way to send malware or viruses into your system. To show an IP-based route scan, check the details under the show ip route option. This might also show if any of the other subjects are being used by unauthorized users.
There are many reasons why a Cisco IP command notations can help you troubleshoot your network. Of course, Cisco products have been designed to be easy to use, but they also provide maximum functionality. If you know the proper syntax for the various commands, you can avoid a lot of common problems and be able to solve more complex issues quickly.
Of course, if you don’t know the syntax of the various Cisco IP command notations, then you should not attempt to learn them from Cisco documentation. Instead, contact a professional Cisco specialist to assist you in troubleshooting your network’s IP based issues. They will be able to show you the proper syntax for each command and how it should be used to address a particular problem. You’ll probably also find that their experience will be helpful as well. Regardless of whether you’re trying to troubleshoot network issues in a small company or a large company, it’s critical that you have a solid grasp on all of the Cisco IP command notations.
You never know when an unauthorized user may be using your network for illicit purposes. When you see “unaase” instead of the IP address, there’s a good chance that someone is using your network without your permission. By using the show command, you can find out exactly who is doing this and make sure that you take steps to stop them before you end up in court. Hopefully, this will put your mind at ease and allow you to focus on your company and preventing unauthorized use of your network.
