Field Description
Attempt
It is enabled in an NBMA environment, such as Frame Relay,
X.25 or ATM. It indicates that OSPF router does not receive the
message from a certain neighbor router within a period of time,
but still attempts to send Hello packet to the adjacent routers for
their communications with a lower frequency.
Init

neighbor router, but its IP address is not contained in the Hello

router and neighbor router has been established. DR and BDR
can be selected in this state (or higher state).

exchange, so that it can obtain the latest link state information
Exchange It indicates that OSPF router sends DD packet to its neighbor
routers to exchange link state information
Loading
In this state, OSPF router requests neighbor routers based on
the updated link state information from neighbor routers and its
expired information, and waits for response from neighbor
routers

that have established neighbor relation has been completed,
and their link state databases have been consistent
