In this episode you will learn:

- The OSPF DR/BDR election only occurs on multi-access networks to reduce LSA flooding.

- The router with the highest OSPF interface priority (0-255) wins the DR election; a priority of 0 makes a router ineligible.

- The highest router ID is used as the tie-breaker if interface priorities are equal.

- The election process is non-preemptive; a new router with a higher priority will not take over an already-elected DR.

- DROTHERs form a FULL adjacency with the DR and BDR, but only a 2-WAY state with other DROTHERs.
