To determine the IP addresses of neighboring routers, which command can be used after identifying the ports?

1. #show ip interface

2. #show routing-table

3. #show running-config

4. #show cdp neighbors detail

The correct answer is: #show running-config

To determine the IP addresses of neighboring routers, the appropriate command to use is the command that provides detailed information about the devices connected via Cisco Discovery Protocol (CDP). The command that achieves this is one that specifically reveals information about the CDP neighbors, including their IP addresses, device IDs, and the interfaces they are connected to. The command that would effectively display this information is the one that specifies "cdp neighbors detail." By using this command, you gain access to detailed information regarding each neighboring device, including essential data such as their IP addresses, which is crucial for network troubleshooting or management tasks. This level of detail helps network administrators understand not just what devices are present, but also the relationships and configurations present within the network. The reason the other options do not provide the needed information includes: - The command regarding interfaces primarily shows the status and configuration of the interfaces on the local router and does not give details about neighboring devices. - The routing-table command displays the routing information and paths to various network destinations but does not include specific details about neighboring routers. - The running-config command displays the current configuration of the local device, which includes settings and interfaces but not any dynamic neighbor relationship information. Thus, for identifying neighboring routers and their IP addresses, the
