Interface Delay Interval (secs) — Enter the OSPF Transit Delay for the specified interface. This
•
specifies the estimated number of seconds it takes to transmit a link state update packet over the
selected interface. Valid values range from 1 to 3600 seconds (1 hour). The default value is 1 second.
• State — The current state of the selected Virtual Link. One of:
– 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 are set to their initial values. All
interface timers are disabled, and there are 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 contains 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 is 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.
Neighbor State — The state of the Virtual Neighbor Relationship.
•
• Retransmit Interval — Enter the OSPF retransmit interval for the specified interface. This is the
number of seconds between link-state advertisements for adjacencies belonging to this router
interface. This value is also used when retransmitting database descriptions and link-state request
packets. Valid values range from 1 to 3600 seconds (1 hour). The default is 5 seconds.
Metric — The metric value used by the virtual link.
•
• Delete — Removes the specified virtual link from the router configuration.
Creating a New Virtual Link
1. Open the OSPFv3 Virtual Link Configuration page.
2. Select Create New Virtual Link from the drop-down menu to define a new virtual link.
3. Enter the Neighbor Router ID.
