In OSPF, which state indicates that routers are exchanging routing information to form a complete topology database?

• A. Init
• B. Exstart
• C. Full
• D. Loading

Answer: (C)

In OSPF (Open Shortest Path First), the state that indicates routers are exchanging routing information to form a complete topology database is the Full state. When routers reach the Full state during the OSPF adjacency establishment process, it signifies that they have successfully exchanged LSAs (Link State Advertisements) and have a complete and synchronized view of the network topology. During the initial adjacency formation, routers progress through several states. In the Full state, each router has a complete database, which means that they can now make routing decisions based on the synchronized information. This state is key for OSPF's operation, as it ensures that all routers within the OSPF area have an identical view of the network, allowing effective path calculation and routing. The other states represent different stages of the OSPF neighbor relationship. For example, in the Init state, routers have detected each other but have not yet completed the exchange of information. The Exstart state is where the routers start the process of negotiating the parameters for the exchange, such as which router will be the master and which will be the slave. The Loading state occurs when routers are in the process of receiving and processing the LSAs but haven't completed the exchange. Thus, understanding these states
