""The OSPF interface priority is the parameter that controls DR election. Its default value is “1”. When OSPF interface priority is “0”, the router is not eligible to become a DR. If a router comes up on a network segment and there are no other routers there already, it will become a DR. If there is an existing DR (or BDR), the new router will NOT attempt to preempt them. If several routers come up at roughly the same time (or the DR fails), a new DR election process will be triggered. The router with the highest priority value then will become a DR.
If the priorities are the same, the router with the highest router ID becomes the DR
The OSPF router id is either manually created by using the ospf router-id command or generated automatically by follwing this process. Use the address of the loopback 0 interface if no loopback then use the highest IP address of any interface if no interface exists, set the router-ID to 0.0.0.0
