In the DR/BDR selection process on broadcast networks, which criterion is primarily used to determine the Designated Router (DR)?
The router with the highest interface priority
The router with the lowest Router ID
The router with the highest routing cost
The router with the lowest interface bandwidth
In OSPF broadcast networks, the router with the highest interface priority becomes the Designated Router (DR). The interface priority is a configurable value ranging from 0 to 255, with the default being 1. A higher value increases the likelihood of a router becoming the DR. If interface priorities are the same, the router with the highest Router ID is selected. Interface bandwidth and routing cost do not influence the DR/BDR election.
