Which command provides the list of networks being advertised in EIGRP?

1. #show ip route

2. #show ip eigrp neighbors

3. #show eigrp topology

4. #show running-config

The correct answer is: #show eigrp topology

The command that provides the list of networks being advertised in EIGRP is indeed associated with the EIGRP topology, which maintains information about the routes that EIGRP knows about and has advertised. When you execute the command to view the EIGRP topology, you can see not only the routes that are currently in use but also each route’s state, associated metrics, and how these routes are learning about each other. This command is crucial for network administrators since it provides insights into how EIGRP is functioning within the network, including the paths it's advertising to peers. It helps in verifying that the correct networks are being propagated and can aid in troubleshooting any routing issues or verifying configuration changes. In contrast, commands like showing the IP route would display the routing table but not specifically highlight the EIGRP advertising process, while showing EIGRP neighbors provides information about adjacent routers in the EIGRP topology rather than the advertised networks. Lastly, the running configuration command reveals the actual configuration of the router but doesn't explicitly show what networks are being advertised by EIGRP.
