This is the complete information for entry 2.2.2.0/24Confirmation message *FULLFigure 8-2-4 OSPF neighbor relationship establishment processDown: The initial state of the OSPF router. In the Down state, the OSPF process has not yet exchanged information with any neighbors.. Init: The initialization phase, which means that a Hello message has been received from the neighboring router, but the Router ID of this router is not found among the neighbors listed in the message, that is, the other party has not received the Hello message from this router.. Two-Way: The two-way phase indicates that both parties have received a Hello message from each other and established a neighbor relationship. In a multi-access network, two routers with a DROther interface state will stay in this state, otherwise they will continue to move to the next state. The Two-Way state is the most basic relationship between OSPF neighbors, but routers in this relationship cannot share routing information with each other; to share routing information, routers need to establish an adjacency relationship with each other.. Exstart: ready to start the exchange phase. the routers use the Hello group to negotiate the master/slave relationship between them. the router with the highest RouterID becomes the master router. Once the neighboring routers have established the master/slave role between them, they enter the Exchange state and start sending routing information.. Exchange: starts the exchange phase. the router describes the local LSDB with a DBD (DataBase Description) message and sends it to its neighbors. If any router receives information about a link that is not in its database, that router requests complete information about the link from its neighbors. The complete routing information is exchanged in the "Loading" state.. Loading: In the loading phase, the router sends LSR messages to request detailed information about the other party's routing entries from its neighbors. When a router receives an LSR, it responds with an LSU. The LSU contains the exact LSA, and the router receiving the LSU needs to acknowledge the router sending the LSU using the LSAck.
