After you configure the Loopback0 interface, which command can you enter to verify the status of the interface and determine whether fast switching is enabled?

The `show ip interface loopback 0` command displays detailed IP-related information for the specified interface, including its IP address, status, protocol status, and whether fast switching is enabled or disabled, focusing on Layer 3 aspects.

The `show run` command displays the router's saved configuration but does not show real-time operational status or specific interface features like fast switching for a particular interface.

The `show interface loopback 0` command displays general Layer 2 and Layer 1 status of the interface (e.g., line protocol status, errors), but it does not provide IP-specific details like fast switching status.

The `show ip interface brief` command provides a concise summary of IP addresses and interface status for all interfaces, but it lacks the detailed information, such as fast switching status, for a specific interface.
