What is the neighbor state when an OSPFv3 adjacency is established?
When an OSPFv3 adjacency is established, the neighbor state is Full. This state indicates that the OSPF routers have successfully exchanged and synchronized their databases, meaning they have a complete and accurate view of the network topology. The 2-way state, on the other hand, signifies that a hello relationship has been established but does not indicate full adjacency.
When we talk about adjacency established, we are talking about full state. A 2-way state means a neighboring relationship established and indicates that the router receives Hello packets that contain its router ID. If the router does not need to establish adjacencies with its neighbor, the OSPF neighbor status remains 2-way. Otherwise, the neighbor status enters the Exstart state.
