State Shows the state of the neighboring routers. Possible values are:
• Down- initial state of the neighbor conversation - no recent
information has been received from the neighbor.
• Attempt - no recent information has been received from the
neighbor but a more concerted effort should be made to
contact the neighbor.
• Init - a Hello packet has recently been seen from the neighbor,
but bidirectional communication has not yet been established.
• 2 way - communication between the two routers is bidirectional.
This is the final state between two routers, both of which are
non-designated routers or back-up designated routers.
• Exchange start - the first step in creating an adjacency between
the two neighboring routers, the goal is to decide which router
is the master and to decide upon the initial DD sequence
number.
• Exchange - the router is describing its entire link state database
by sending Database Description packets to the neighbor.
• Loading - Link State Request packets are sent to the neighbor
asking for the more recent LSAs that have been discovered
(but not yet received) in the Exchange state.
• Full - the neighboring routers are fully adjacent and they will
now appear in router-LSAs and network-LSAs.
Dead Time Shows the amount of time, in seconds, to wait before the router
assumes the neighbor is unreachable.

Interface Shows the interface of the local router.
Area ID The area ID associated with the interface.
Options An integer value that indicates the optional OSPFv3 capabilities
supported by the neighbor. These are listed in its Hello packets.
This enables received Hello Packets to be rejected (that is,
neighbor relationships will not even start to form) if there is a
mismatch in certain crucial OSPFv3 capabilities.
Router Priority Displays the router priority for the specified interface.
