Which command is used to confirm the EIGRP configuration on an interface?

1. show ip eigrp interface

2. show eigrp interface

3. show running-config

4. show ip interface brief

The correct answer is: show ip eigrp interface

The command that confirms the Enhanced Interior Gateway Routing Protocol (EIGRP) configuration on an interface is indeed the command that specifically displays EIGRP interface information. This command provides detailed information about all interfaces on which EIGRP is enabled, including metrics, EIGRP neighbor relationships, and other protocol-specific settings. Using a command focused on EIGRP allows network engineers to quickly verify that the correct configurations are in place for EIGRP to function properly on the specified interfaces, ensuring optimal routing within the network. Other commands, while useful for broader network monitoring and configuration validation, do not specifically target the EIGRP configurations tied to interfaces. For example, the command that displays the running configuration will show all configurations, but not specifically those tied only to EIGRP. The remaining commands provide different types of information that may assist in understanding the interface’s status or general IP interface details, but they lack the focused clarity on EIGRP configurations required for this inquiry.
