Table 189: show (ospf | ospf3) neighbor Output Fields (continued)
Level of OutputField DescriptionField Name
All levelsState of the neighbor:
• Attempt—Valid only for neighbors attached to nonbroadcast networks. It
indicates that no recent information has been received from the neighbor,
but that a more concerted effort must be made to contact the neighbor.
• Down—Initial state of a neighbor conversation. It indicates that no recent
information has been received from the neighbor. Hello packets might
continue to be sent to neighbors in the Down state, although at a reduced
frequency.
• Exchange—Routing device is describing its entire link-state database by
sending database description packets to the neighbor. Each packet has a
sequence number and is explicitly acknowledged.
• ExStart—First step in creating an adjacency between the two neighboring
routing devices. The goal of this step is to determine which routing device is
the master, and to determine the initial sequence number.
• Full—Neighboring routing devices are fully adjacent. These adjacencies appear
in router link and network link advertisements.
• Init—A hello packet has recently been sent by the neighbor. However,
bidirectional communication has not yet been established with the neighbor.
This state may occur, for example, because the routing device itself did not
appear in the neighbor's hello packet.
• Loading—Link-state request packets are sent to the neighbor to acquire more
recent advertisements that have been discovered (but not yet received) in
the Exchange state.
• 2Way—Communication between the two routing devices is bidirectional. This
state has been ensured by the operation of the Hello Protocol. This is the
most advanced state short of beginning adjacency establishment. The
(backup) designated router is selected from the set of neighbors in state
2Way or greater.

the identifier marks database entries that originated from the local routing
