As a network engineer, you need to control which router is elected as the DR in a broadcast network segment running a OSPF link-state routing protocol. What is the most effective method to achieve this?
Set a lower administrative distance on the desired router.
Increase the interface priority value on the desired router.
Decrease the link cost on the desired router's interface.
To control the election of the Designated Router (DR) in a broadcast network segment using a link-state routing protocol like Open Shortest Path First (OSPF), you should increase the interface priority on the desired router. The router with the highest interface priority is elected as the DR. If interface priorities are equal among routers, the router with the highest router ID is chosen, but manipulating the interface priority directly provides more control over the DR election. Assigning a higher router ID may not guarantee DR election if another router has a higher interface priority. Decreasing the link cost affects path selection metrics, not DR election. Adjusting the administrative distance affects route preference between different routing protocols, not the DR/BDR selection within the same protocol.
