2-Way
- In this state, communication between the two routers is bidirectional. This has
been assured 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 2-Way or greater.
Exchange Start
- 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 DD sequence number. Neighbor conversations in this state or
greater are called adjacencies.
Exchange
- In this state the router is describing its entire link state database by sending
Database Description packets to the neighbor. In this state, Link State Request Packets
may also be sent asking for the neighbor's more recent LSAs. All adjacencies in Exchange
state or greater are used by the flooding procedure. These adjacencies are fully capable of
transmitting and receiving all types of OSPF routing protocol packets.
Loading
- In this state, 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
- In this state, the neighboring routers are fully adjacent. These adjacencies will
now appear in router-LSAs and network-LSAs.
Events
- The number of times this neighbor relationship has changed state, or an error
has occurred.
Permanence
- This variable displays the status of the entry. 'dynamic' and 'permanent' refer to
how the neighbor became known.
Hellos Suppressed
- This indicates whether Hellos are being suppressed to the neighbor.
Retransmission Queue Length
- The current length of the retransmission queue.
Up Time
- The Up Time of the OSPF neighbor, which says how long the neighbor is active
Restart Helper Status
- The status of a helpful neighbor can be the following:
Not Restarting
- The neighbor is not restarting.
Planned Restart
- The neighbor is restarting due to a user initiated failover.
Unplanned Restart
- The neighbor is restarting due to an unplanned failover.
Restart Reason
- The reason for the last restart.
Remaining Grace Time
- The number of seconds remaining in the current graceful restart
interval. This row is only included if the router is currently acting as a restart helper for the
neighbor.
Restart Helper Exit Reason
- The reason behind the last restart of the a helpful neighbor can be
the following:
None
- Graceful restart has not been attempted.
In Progress
- Restart is in progress.
Completed
- The previous graceful restart completed successfully.
Timed Out
- The previous graceful restart timed out.
Topology Changed
- The previous graceful restart terminated prematurely because of
a topology change.
Command Buttons
Refresh
- Refresh the data on the screen with the present state of the data in the switch.
