Field Description
Area ID Area ID
Down The initial state for OSPF to establish neighbor relation, which indicates that
the OSPF router has not received the message from a certain neighbor router
within a period of time.
Attempt Enabled in the NBMA environment, such as Frame Relay, X.25 or ATM. It
indicates that OSPF router has not received the message from a certain
neighbor router within a period of time, but still attempts to send a Hello
packet to the adjacent routers for their communications with a lower
frequency.
Init Indicates that the OSPF router has received a Hello packet from a neighbor
router, but its IP address is not contained in the Hello packet. Therefore, a
two-way communication between them has not been established.
2-Way It indicates that a two-way communication between an OSPF router and a
neighbor router has been established. DR and BDR can be selected in this state
(or higher state)
ExStart In this state, the router determines the sequence number of the initial
database description (DD) packet used for data exchange, so that it can obtain
the latest link state information.
Exchange Indicates that the OSPF router sends DD packets to its neighbor routers to
exchange link state information.
Loading In this state, OSPF router requests routes from the neighbor based on the
updated link state information from neighbor routers and its expired
information, and waits for response from neighbor routers.
Full Indicates that database synchronization between the routers has been
completed, and their link state databases are consistent.
