Non-Configurable Data
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 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. The router attempts to form adjacencies to both the Designated
Router and the Backup Designated Router.
Neighbor State - The state of the Virtual Neighbor Relationship.
Command Buttons
Configure Authentication - Display a new screen where you can select the
authentication method for the virtual link.
Submit - Send the updated configuration to the switch. Configuration changes take effect
immediately. These changes will not be retained across a power cycle unless a save is
performed.
Delete - Removes the specified virtual link from the router configuration.
