In a broadcast network running OSPF, which criterion is most significant in determining the election of the Designated Router (DR)?
The router with the longest uptime in the network
The router with the lowest MAC address on the interface
The router with the highest Router ID
The router with the highest interface priority value
In OSPF broadcast networks, the primary factor for electing the Designated Router (DR) is the interface priority value assigned to each router. The router with the highest interface priority becomes the DR. If multiple routers have the same highest priority, the router with the highest Router ID is selected. Interface priority is configurable and allows network administrators to influence DR election, making it the most significant criterion in the selection process.
