CCNA: Cisco Certified Network Associate — Question 212

You have configured a router with an OSPF router ID, but its IP address still reflects the physical interface.
Which action can you take to correct the problem in the least disruptive way?

Answer options

• A. Reload the OSPF process
• B. Specify a loopback address
• C. Reboot the router
• D. Save the router configuration

Correct answer: A

Explanation

Reloading the OSPF process will refresh the OSPF configuration and take into account the new router ID without causing a full router reboot or disrupting the configuration. Specifying a loopback address is a good practice for stability but does not address the immediate issue. Rebooting the router would cause unnecessary downtime, and saving the configuration does not affect the OSPF process directly.
