Which command is used to configure a name on the router?

To configure a name on a router, the command that sets the router's hostname is essential. When you use the command that includes "hostname" followed by the desired name (in this case, "CL1"), it directly assigns that name to the router's configuration. The hostname is crucial as it helps in identifying the router on the network and makes it easier to manage, especially when there are multiple devices in the environment.

This command effectively changes the default identity of the router to the specified name, which will be displayed in the command prompt and can help network administrators easily recognize and access the router during configuration or troubleshooting tasks. It's a fundamental step in router configuration, paving the way for better organization and clarity within network management practices.
