Therefore, they have no information about each other's status as neighbors, and they do not list each other in the output of the show ip ospf neighbor command. In step , R1 sends the first Hello, so R2 knows about R1's existence as an OSPF router. At this point, R2 lists R1 as a neighbor, with its interim state as init.The process continues to step , where R2 sends back a Hello. this message tells R1 that R2 exists, and it transitions R1 to the 2-way state. At step , R2 receives the next Hello from R1, so R2 can also transition to the 2-way state.To get more insight into why the router transitions to the next state, revisit the details in these messages and look for the comments listed as "seen". When a router receives a Hello from a potential neighbor, and the parameters of that potential neighbor match those of the local router, the local router assumes that it has seen a new legitimate neighbor on the link. For example, the message in the diagram labeled Step 3, from R2 to R1, lists "saw [1 1.1]", meaning that R2 received a previous Hello from R1 (in Step 2), and R2 thinks all parameters match, so the two routers can become neighbors.Once these early steps are completed, each router has reached a 2-way (bidirectional) state with its neighbors. At this point, there are two main facts.The router receives a Hello from a neighbor,and that router's own RID is listed as seen by the neighbor.The router checks all parameters in the Hello received from the neighbor and there are no problems. The router is willing to become a neighbor.
