What command would you use to check the status of the routing protocols on a Junos device?

To check the status of the routing protocols on a Junos device, the command "show routing protocol" is appropriate because it specifically queries the operational status of all routing protocols configured on the device. This command provides detailed information regarding the protocols in use, their state, and relevant statistics, allowing administrators to effectively monitor and troubleshoot the routing layer of the network.

Understanding the routing protocols and their status is crucial for network reliability and performance, and this command encapsulates that focus. The clarity and specificity of this command enable users to quickly ascertain if any routing protocol issues exist, such as adjacency problems or configuration errors.

Other options do not align with the Junos command syntax or do not provide the same level of detail regarding routing protocols.
