What happens when you use the command 'show ip protocols'?

Using the command 'show ip protocols' provides insight into the routing protocols that are currently configured and operating within a router. This command displays essential information such as the routing protocols in use, the networks being advertised, and certain parameters related to these protocols, like timers and metrics.

This command is particularly useful for network engineers and administrators who need to troubleshoot or verify the routing configuration of the device. By employing this command, they can ensure that the router is successfully exchanging routing information with other devices in the network, which is crucial for efficient network communication and data flow.

The other options listed do not align with the function of the command. For instance, displaying CPU usage statistics, resetting routing protocols, or updating the routing table are not tasks performed by 'show ip protocols'. Thus, the command's purpose is explicitly centered on providing a detailed view of routing protocol operations on the router.
