What does the output display when using the #show eigrp topology command?

1. The list of all routing protocols in use

2. The status of all neighbors

3. All EIGRP routes, their states, and distances

4. The configuration of EIGRP settings

The correct answer is: All EIGRP routes, their states, and distances

When using the #show eigrp topology command, the output provides a comprehensive view of all EIGRP routes that the router knows about. This includes critical information such as the states of those routes, which indicate whether the routes are feasible, active, or passive, as well as the distances associated with each route. The distances reflect the metric that EIGRP uses to determine the best path to a destination, which can include composite metrics based on bandwidth, delay, load, and reliability. This command is vital for network administrators as it helps in understanding the routing decisions EIGRP is making and allows for troubleshooting and optimization of the network routing paths. The visibility into the different states of the routes aids in determining if the routes are reliable, under contention, or down, enabling effective network management. The other options do not accurately reflect the function of the #show eigrp topology command. For instance, listing all routing protocols or the status of neighbors pertains to different commands. Similarly, while understanding EIGRP configurations is important, those details are captured through commands focused on displaying running configurations rather than topology outputs.
