
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.
If you specify an IP address for the neighbor router, the following fields display:
Interface: Shows the interface of the local router in slot/port format.
Area ID: The area ID associated with the interface.
Options: An integer value that indicates the optional OSPF capabilities supported by the neighbor.
These are listed in its Hello packets. This enables received Hello Packets to be rejected (i.e.,
neighbor relationships will not even start to form) if there is a mismatch in certain crucial OSPF
capabilities.
Router Priority: Displays the router priority for the specified interface.
Dead Timer Due: Shows the amount of time, in seconds, to wait before the router assumes the
neighbor is unreachable.
State: Shows the state of the neighboring routers.
Events: The number of times this neighbor relationship has changed state, or an error has occurred.
Retransmission Queue Length: An integer representing the current length of the retransmission
queue of the specified neighbor router Id of the specified interface.
