Question

What does the command execute router ospf clear ospf process do?

a) Clears OSPF configuration settings
b) Resets OSPF process
c) Initiates OSPF routing updates
d) Performs a router diagnostic process

Answer 1

The command 'execute router ospf clear ospf process' resets the OSPF process on a router, causing all OSPF neighbor relationships to restart and re-establish.

Therefore, the correct answer is: option b) Resets OSPF process.

Step-by-step explanation:

OSPF uses IP multicast to send link-state updates. This ensures less process resource consumption on routers that do not listen to OSPF packets. Updates are only sent in case routing changes occur instead of periodically.

The command "execute router ospf clear ospf process" is used in networking to restart the OSPF process on the router. The result of executing this command is that all OSPF neighbor relationships will be torn down, and the OSPF process will go through the full initialization process again.

This can be useful in situations where you need to force the router to re-establish OSPF adjacencies or if there has been a significant configuration change that needs to be applied immediately.
