What command would you use to verify EIGRP configurations on interfaces?

1. show ipv6 eigrp routers

2. show ipv6 eigrp interfaces

3. show eigrp neighbors

4. show ipv6 protocols

The correct answer is: show ipv6 eigrp interfaces

The use of the command that displays EIGRP configurations specifically related to interfaces is essential for network troubleshooting and configuration verification in an EIGRP environment. This command provides details about which interfaces are configured to participate in EIGRP for IPv6, including their states and metrics. When you execute the command to check EIGRP interfaces, it shows a list of all interfaces that have EIGRP enabled and their corresponding parameters. This is particularly useful for ensuring that all intended interfaces are part of the EIGRP routing process, helping identify any potential misconfigurations or issues related to routing. In contrast, other commands serve different purposes. For instance, there is a command that verifies the routers' relationships in the EIGRP process, providing insights into neighbor relationships rather than interface configurations. Another command displays general routing protocol information rather than focusing specifically on EIGRP interfaces. Similarly, a separate command may include protocol configurations but will not provide the detailed interface-level information that is critical for effective troubleshooting. Thus, using the command to verify EIGRP interfaces is the most direct way to check how EIGRP is configured across the network’s interfaces.
