What will occur if the OSPF adjacency process is fully successful?

When the OSPF adjacency process is fully successful, the state of the adjacency is considered to be "Full." In this state, two OSPF routers have successfully completed all necessary steps to establish a fully functional peer connection. This involves several stages, including establishing a neighbor relationship, exchanging routing information, and ensuring that both routers have synchronized their link-state databases.

In the Full state, routers can now freely share and exchange routing information with each other, which is key to the operation of OSPF. This state enables optimal routing decisions to be made based on the complete and up-to-date information each router has about the network's topology.

The other stages in the OSPF adjacency process—such as Init, which is the initial state where a router recognizes a neighbor but has not yet completed the handshake, and Loading, where the routers are still exchanging routing information and database contents—are part of the overall adjacency process but do not indicate successful completion. The Exchange phase precedes Full, representing the stage where database information is being shared but not yet fully synchronized. Thus, achieving Full is crucial for OSPF to function effectively and optimally in a network environment.
