The OSPF packets shown have been exchanged between two neighbors. What state is the OSPF adjacency in?
- A. The adjacency state is full. The routers are exchanging database description packets to notify each other that all link state advertisements have been received.
- B. The adjacency is in the ex start state. The routers have exchanged database description packets, but still have to negotiate the starting sequence number.
- C. The adjacency state is two way because both routers have received a database description packet.
- D. The adjacency is in the exchange state. The next step is to exchange link state request and link state update packets.
Correct Answer: D 🗳️

- B. The system interface is missing in one configuration so OSPF will not operate correctly.
- C. The interface type settings differ, but OSPF will still operate correctly.
- D. Both routers will generate OSPF Hello packets.
