An engineer is examining an Open Shortest Path First (OSPF) interface on a router and notices that no DR/BDR elections occur on that interface, and OSPF packets are being sent to the multicast address 224.0.0.5. What OSPF network type is the interface using?
Point-to-Multipoint
Point-to-Point
Non-Broadcast
Broadcast
The OSPF point-to-point network type does not perform Designated Router (DR) or Backup Designated Router (BDR) elections because there are only two routers on the link, making such elections unnecessary. In this network type, OSPF packets are sent to the multicast address 224.0.0.5. Point-to-multipoint networks also avoid DR/BDR elections but are used in scenarios with multiple routers in a hub-and-spoke topology and may require additional configuration. Broadcast networks do have DR/BDR elections and use both multicast addresses 224.0.0.5 and 224.0.0.6. Non-broadcast networks require manual neighbor configuration and also perform DR/BDR elections.
