On a broadcast network, if the DR priorities of two interfaces connecting two routers are...

In OSPF (Open Shortest Path First), routers connected over broadcast networks (like Ethernet) elect a Designated Router (DR) and Backup Designated Router (BDR). DR election is based on the interface priority. If the priority is set to 0, the router cannot become a DR or BDR.

When both routers have a priority of 0, no DR or BDR will be elected, and since the election fails, the neighbor relationship between the two routers will not advance beyond the 2-Way state. In this state, the routers acknowledge each other but do not exchange routing information in detail (as they only form full adjacency with the DR/BDR).

Therefore, the OSPF neighbor relationship remains in the 2-Way state.
