Which statement is false?

  • A A password has been configured on the local OSPF router but is not shown in the output.
  • B The Hello packet is being sent from an OSPF router with ID 0.0.0.112.
  • C The two FortiGate devices attempting adjacency are in area 0.0.0.0.
  • D One FortiGate device is configured to require authentication, while the other is not.
Explanation

An OSPF Hello with AuthType 0 uses no authentication. An authentication-type mismatch shows that the receiving neighbor expects a different authentication type, but it does not prove that a password is configured on that local FortiGate. The Hello identifies router ID 0.0.0.112 and area 0.0.0.0; matching area processing has occurred before the authentication mismatch is reported.
