Summary
Now that you have reviewed some Cisco IOS software basics, you can begin to configure your router.
Remember:
• You can use the question mark (?) and arrow keys to help you enter commands.
• Each command mode restricts you to a set of commands. If you are having difficulty entering a
command, check the prompt, and then enter the question mark (?) for a list of available commands.
You might be in the wrong command mode or using the wrong syntax.
• If you want to disable a feature, enter the keyword no before the command; for example, no ip
routing.
• Save your configuration changes to NVRAM so that they are not lost if there is a system reload or
power outage.
Where to Go Next
To configure your router, go to Chapter 1, “Basic Router Configuration,” and Chapter 2, “Sample
Network Deployments.”
