Question

Two routers, R1 and R2, are connected through a Layer 2 switch on the same Ethernet segment and are both configured for single-area OSPFv2. The interfaces reach the FULL state, but the network engineer notices that a DR and BDR are elected on this segment. R2 has the higher OSPF priority. Which statement correctly explains this behavior?

Accepted Answer

The interfaces use the OSPF broadcast network type by default, which elects a DR/BDR to reduce LSA flooding on the multi-access segment.

Answer

The interfaces use the OSPF point-to-point network type by default, and a DR/BDR is always elected on point-to-point links.

Answer

A DR/BDR election only occurs because OSPF authentication is enabled between the two routers.

Answer

The DR/BDR election happens because the routers are in different OSPF areas connected across the switch.
