What command displays EIGRP for IPv6 neighbor information?

1. show ipv6 eigrp neighbors

2. show ipv6 protocols

3. show ipv6 eigrp interfaces

4. show ipv6 eigrp topology

The correct answer is: show ipv6 eigrp neighbors

The command that displays EIGRP for IPv6 neighbor information is indeed "show ipv6 eigrp neighbors." This command is specifically designed to provide details about the EIGRP neighbors that a router has established under the IPv6 protocol. It shows the state of the relationships with neighboring routers that are participating in the EIGRP routing process for IPv6, such as the neighbor's IP address and the interface through which the neighbor is reachable. When you use this command, you get important information, such as the neighbor's hold time, the uptime of the adjacency, and the metric used for route calculation. This is critical for troubleshooting and understanding the EIGRP operation in an IPv6 environment. The other options focus on different aspects of EIGRP for IPv6. For instance, "show ipv6 protocols" provides general information about the routing protocols configured on the router, not specifically focused on neighbors. "Show ipv6 eigrp interfaces" displays the interfaces that are participating in EIGRP, while "show ipv6 eigrp topology" details the EIGRP topology table, which holds information about network routes but does not specifically show neighbor relationships. Each of these commands serves a unique purpose and provides different information related to EIG
