What command would you use to display the routing table on a Cisco router?

To view the routing table on a Cisco router, the command "show ip route" is employed. This command provides a detailed listing of all routes that the router has in its routing table, including their destinations, next hops, and metrics. It is essential for network administrators to assess the paths that data packets will take as they traverse networks.

The information presented by this command includes routes learned via dynamic routing protocols, static routes, and directly connected networks. Understanding the routing table is crucial for troubleshooting and optimizing network performance, as it outlines how traffic is managed across different network segments.

Other commands related to router configurations and interfaces do not provide the routing information. For example, while "show running-config" displays the current configuration of the router, it does not give details about the active routes. "Show ip interface" focuses on the status of the interfaces, and "display routing-table" is a command used on other devices, such as those running different operating systems, but is not applicable in a Cisco environment. Thus, "show ip route" is the command specifically designed for this purpose on Cisco routers.
