Status Displays the state of the relationship with the neighbor listed in this instance.
An event invokes each state change, such as a received hello packet. This
event produces different effects, depending on the current state of the
neighbor. Also, depending on the state of neighbor change, the routers
initiate a DR election.
Possible values:
down
(default setting)
This value indicates the initial state of a neighbor conversation or a
router terminated the conversation due to expiration of the "Dead
Interval [s]" timer.
attempt
The state is only valid for neighbors attached to NBMA networks. The
value indicates that information from the neighbor remains unresolved.
The router actively attempts to contact the neighbor by sending the
neighbor hello packets in the interval specified in "Hello Interval [s]".
init
The router has recently seen a hello packet from the neighbor.
However, the router has only established uni-directional communication
with the neighbor. For example, the router ID of this router is missing
from the hello packet of the neighbor. The associated interface lists
neighbors in this state, or higher, when sending hello packets.
twoway
Communication between the 2 routers is bidirectional. The router
verifies the operation by examining the contents of the hello packet. The
routers elect a DR and BDR from the set of neighbors while in or after
the 2-way state.
exchangeStart
The value indicates the first step in creating an adjacency between the
2 neighboring routers. The goal of this step is to decide which router is
the master and to decide upon the initial "Sequence" number.
exchange
The router is announcing its entire link state database by sending
Database Description (DD) packets to the neighbor. The router
explicitly acknowledges each DD packet and each packet has a
sequence number. The adjacencies only allow 1 DD packet to be
outstanding at any time. In this state, the router sends LS Request
packets asking for up-to-date database information. The adjacencies
are fully capable of transmitting and receiving OSPF routing protocol
packets.
loading
The router sends LS Request packets to the neighbor inquiring about
the outstanding database updates sent in the exchange state.
full
The neighboring routers are fully adjacent. The adjacencies now appear
in router LSAs and network LSAs.
Dead Time Displays the amount of time remaining before the router declares the
neighbor status as down. The timer initiates the count down after the router
receives a hello packet.
