An OSPF hello packet has been sent, but bidirectional communication has not been established.
What is the state of the OSPF adjacency?
A . Down
B . Init
C . Exchange
D . Loading
Answer: A
Explanation:
Down is the first OSPF neighbor state. It means that no information (hellos) has been received from this neighbor, but hello packets can still be sent to the neighbor in this state. Incorrect Answers:
B: The Init state specifies that the router has received a hello packet from its neighbor, but the receiving router’s ID was not included in the hello packet. Reference:
