Which command will display the full contents of the EIGRP topology table?

Displaying the full contents of the EIGRP topology table can be effectively done using the command that specifies the request for all links within the topology, which is why the correct choice involves "show ip eigrp topology all-links." This command provides a comprehensive view of all routes learned via EIGRP, including both feasible successors and successors, thus giving a detailed insight into the network topology as recognized by EIGRP.

The command retrieves all relevant information about each EIGRP route, allowing network engineers to analyze not only the current successor routes but also the backup routes that the EIGRP can utilize if the primary path fails. This information is crucial for troubleshooting, performance monitoring, and ensuring the overall health of the EIGRP routing protocol within the network.

Other commands mentioned would not provide the complete content of the EIGRP topology table. For instance, the command focused on routing tables would only show EIGRP-learned routes in the main routing table, while commands related to EIGRP neighbors would provide information mostly about direct connections with neighboring routers rather than a detailed picture of the EIGRP topology itself.
