In this episode you will learn:

- The function of DR/BDR elections on OSPF broadcast networks (like Ethernet) to reduce adjacencies.

- How OSPF uses multicast addresses 224.0.0.5 and 224.0.0.6 on broadcast networks.

- Why OSPF point-to-point networks do not elect a Designated Router (DR) or Backup Designated Router (BDR).

- Common exam traps like mismatched network types or timers preventing OSPF adjacency.

- The DR election process: highest OSPF priority, then highest router ID as the tiebreaker.
