State The communication state for two adjacent routers:
Down: This is the 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
non-broadcast networks. It indicates that no recent
information has been received from the neighbor, but that
the router is attempting to contact the neighbor by sending
Hello packets.
Init: A Hello packet has recently been seen from the neighbor.
However, bidirectional communication has not yet been
established with the neighbor.
2-Way: Communication between the two routers has been
established. This is the most advanced state short of
beginning adjacency establishment. Note that both the
Designated Router and Backup Designated Router are
selected from the set of neighbors in state 2-Way or greater.
ExStart: This is the first step in creating an adjacency between the
two neighboring routers. The goal of this step is to decide
which router is the master, and to decide upon the initial
sequence number. Neighbor conversations in this state or
greater are called adjacencies.
Exchange: The router is describing its entire link state database by
sending database description packets to the neighbor.
(Each database description packet has a sequence number,
and is explicitly acknowledged.) All adjacencies in
Exchange state or greater are used by the flooding
procedure. In fact, these adjacencies are fully capable of
transmitting and receiving all types of OSPF routing
protocol packets.
Loading: Link State Request packets are sent to the neighbor asking
for more recent advertisements that have been discovered
(but not yet received) in the exchange state.
Full: The neighboring routers are fully adjacent. These
adjacencies will now appear in router links and network
links advertisements.
Events The number of events encountered that cause a neighbor state change
since boot up.
