Field Description
Area ID Area ID
Down
Initial state of a neighbor conversation. It
indicates that there has been no recent
information received from the neighbor.
Attempt
This state is only valid for neighbors
attached to NBMA networks, such as
Frame Relay, X.25 and ATM.
It indicates that the OSPF router does
not receive information from the
neighbor router recently, but that an
effort should be made to maintain the
contact with the neighbor by sending
Hello packets in a low frequency.
Init
It indicates that the OSPF router has
received a Hello packet from the
neighbor router, but does not see the IP
address of itself in the Hello packet.
Therefore, a two-way communication
has not been established between the
two routers yet.
2-Way
It indicates that a two-way
communication between the OSPF
router and its neighbor has been
established.
The DR and BDR are selected from the
set of neighbors in 2-Way state or
greater.
