You have changed the router's priority for OSPF to make the router the DR, but the router has not become a DR. What must be done to force the election?
Answer Options
You must use the shutdown and no shutdown commands on the interface with the highest IP address.
In global configuration mode, you must enter the command ospf election force.
In privileged exec mode, you must enter the command clear ip ospf process x.
In privileged exec mode on the DR, you must enter the command clear ip ospf process x.
Correct Answer: D
Explanation
When configuring OSPF for the designated router (DR), if you configure another router with a higher priority, the original DR will remain the current DR. OSPF does not allow for preemption, and therefore you must force the election by clearing the OSPF process on the DR. This will force the DR to relinquish its status. Using the shutdown command on the interface with the highest IP address will not restart the OSPF process. The command ospf election force is invalid; there is no such command. Executing the command clear ip ospf process on any router other than the DR will only restart the OSPF process on the router on which it is executed.
