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?
In OSPF, the 'Full' state indicates that an adjacency relationship has been fully established between neighboring routers. In this state, the routers have exchanged their entire link-state databases and are fully synchronized, allowing them to exchange and synchronize OSPF routing information. Other states like 'Down', '2-way', and 'Attempt' do not indicate a fully established adjacency relationship.
ExStart This is the first step in creating an adjacency between the two neighboring routers. Full In this state, the neighboring routers are fully adjacent. Neighbors that have achieved all 7 states have an Adjacency and thus can exchange and synchronize their OSPF databases.
The 2-Way state indicates that the local router has received a hello packet with its own router ID in the Neighbor field. Thus, bidirectional communication has been established and the peers are now OSPF neighbors
B is the correct answer
