Final answer:
The normal OSPF neighbor state for a router that is neither the DR nor the BDR is the 2-Way state, indicating bidirectional communication without full database exchanges.
Step-by-step explanation:
The normal OSPF neighbor state for a router that is neither the Designated Router (DR) nor the Backup Designated Router (BDR) is 2-Way. In this state, routers have established two-way communication but do not engage in full database exchanges unless they are the DR or BDR. The 2-Way state signifies that the routers have seen each other's Hello packets, implying bidirectional communication. However, OSPF routers that are not the DR or BDR on a network segment will not progress past the 2-Way state with each other.
