• Init - In this state, a Hello packet has recently been seen from the neighbor. However,
bidirectional communication has not yet been established with the neighbor (i.e., the router
itself did not appear in the neighbor's Hello packet). All neighbors in this state (or greater) are
listed in the Hello packets sent from the associated interface.
• 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.
Command Buttons
Refresh - Refresh the data on the screen with the present state of the data in the switch.

Non-Configurable Data
Router ID - The 32 bit integer in dotted decimal format that uniquely identifies the router within the
autonomous system (AS). The Router ID is set on the IP Configuration page. If you want to change
