Field Description
Neighbor State The state of the Virtual Neighbor Relationship.
State The state of the interface:
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.
Metric The metric value used by the Virtual Link.
