Which of the following OSPF states can be used to indicate that an adjacency relationship has been established?
Which of the following OSPF states can be used to indicate that an adjacency relationship has been established?
The correct OSPF state that indicates an adjacency relationship has been established is 'Full.' When OSPF routers reach the 'Full' state, they have fully synchronized their link-state databases and can exchange routing information. The other states, such as 'Down,' '2-way,' and 'Attempt,' represent different stages in the OSPF neighbor establishment process but do not indicate a fully established adjacency.
C. Full is the OSPF state that indicates that an adjacency relationship has been established between two routers.
The OSPF state that indicates an adjacency relationship has been established is "Full". Therefore, option C is the correct answer. The other options refer to different OSPF states: "Down" indicates that no communication is taking place between OSPF neighbors. "2-way" indicates that routers have established bidirectional communication/ neighbor relationship but have not yet formed an adjacency. "Attempt" indicates that a router is actively trying to establish an adjacency with a neighbor.
Two-way simply indicates that routers have exchanged Hello packets. It does not mean establishing adjacency. Full is the final state of OSPF state when adjacency is established
Full state means: Adjacency fully established, routers have synchronized link-state databases and can exchange routing information.
