What is the purpose of the command #show eigrp topology?

1. Displays neighbors in EIGRP

2. Shows the EIGRP packet activity

3. Displays the entire EIGRP for IPv4 network

4. Shows OSPF routing entries

The correct answer is: Displays the entire EIGRP for IPv4 network

The command #show eigrp topology is used to display information about the EIGRP topology database, which includes details about all the EIGRP routes that a router has learned. This command provides a comprehensive view of the EIGRP for IPv4 network, highlighting not only the routes EIGRP has discovered but also their metrics and statuses, which are crucial for understanding the routing decisions EIGRP makes. The EIGRP topology table contains information about both reachable and potential routes, allowing network engineers to troubleshoot and optimize network paths effectively. The routes displayed can include those that are valid, feasible successors, and even those that represent the best paths to reach various destinations. Other options do not focus on the EIGRP topology specifically. For instance, while displaying neighbors in EIGRP or showing packet activity might provide useful information, these functions are accomplished by other commands and do not involve the topology database itself. Similarly, OSPF routing entries are entirely unrelated to EIGRP and are displayed using different commands specific to OSPF configuration and operation.
