Which command displays all EIGRP routes along with their state and feasible distance?

1. #show eigrp interfaces

2. #show eigrp topology

3. #show eigrp neighbors

4. #show ip route

The correct answer is: #show eigrp topology

The command that displays all EIGRP routes along with their state and feasible distance is the command that shows the EIGRP topology. This command provides vital information about each route in the EIGRP routing table, including the metric values, state of each route, and the feasible distance. In EIGRP, the feasible distance is the total metric to reach a destination network, while the route state can indicate whether a route is active or passive. The EIGRP topology table holds information that is essential for understanding how EIGRP calculates the best path for routing decisions. Specifically, it allows network administrators to see all learned routes, their feasibility, and the metrics involved in their selection, which is crucial for troubleshooting and optimizing routing in a network. The other commands focus on different aspects of EIGRP operation: for instance, one command may provide details about EIGRP interfaces and their status, while another focuses on the neighbors that the router is communicating with. A different command might show the overall IP routing table but does not provide the specific EIGRP details needed, such as feasible distance or state for the individual EIGRP routes.
