A network engineer needs to resolve an intermittent network connectivity issue affecting only certain destinations. The engineer suspects a problem with the routing table entries. Which of the following actions should the engineer take FIRST to troubleshoot the issue?
Reboot the router to clear temporary routing inconsistencies
Check the routing table for entries corresponding to the affected destinations
Replace the router with a higher capacity model to handle more routes
Increase the logging level on the router to capture detailed error messages
Checking the routing table entry for specific destinations that are experiencing connectivity issues is the first logical step in troubleshooting. This action confirms whether the router has the correct paths and next-hop addresses to forward packets to those destinations. An incorrect or missing route can lead to packets being dropped or misrouted, which would cause connectivity issues. The other options, although potentially valid in various contexts, do not directly address the initial step of verifying the correctness of the routing table for the destinations in question.
