Field Description
Neighbor State The OSPF interface state, it can be these values:
• Down: This is the initial interface state. In this state, the lower-level protocols have
indicated that the interface is unusable. In this state, interface parameters will be set
to their initial values. All interface timers will be disabled, and there will be no
adjacencies associated with the interface.
• Waiting: The router is trying to determine the identity of the (Backup) Designated
Router by monitoring received Hello Packets. The router is not allowed to elect a
Backup Designated Router or a Designated Router until it transitions out of Waiting
state. This prevents unnecessary changes of (Backup) Designated Router.
• Point-to-Point: The interface is operational, and is connected either to the virtual link.
On entering this state the router attempts to form an adjacency with the neighboring
router. Hello Packets are sent to the neighbor every HelloInterval seconds.
• Designated Router: This router is itself the Designated Router on the attached
network. Adjacencies are established to all other routers attached to the network. The
router must also originate a network-LSA for the network node. The network- LSA will
contain links to all routers (including the Designated Router itself) attached to the
network.
• Backup Designated Router: This router is itself the Backup Designated Router on the
attached network. It will be promoted to Designated Router if the present Designated
Router fails. The router establishes adjacencies to all other routers attached to the
network. The Backup Designated Router performs slightly different functions during
the Flooding Procedure, as compared to the Designated Router.
• Other Designated Router: The interface is connected to a broadcast or NBMA network
on which other routers have been selected to be the Designated Router and Backup
Designated Router either. The router attempts to form adjacencies to both the
Designated Router and the Backup Designated Router.
