CLI Reference Guide
To define an OSPF virtual link, use the area virtual-link command with the
optional parameters. To remove a virtual link, use the no form of this command.
Specifies the area ID assigned to the virtual link. This can be either a decimal
value or a valid IPv4 address. There is no default.
Specifies the router ID associated with the virtual link neighbor. This can be
either a decimal value or a valid IPv4 address. There is no default.
(Optional) Specifies an Instance identifier. To change this ID from an existing
entry, configure the no area command first. The valid setting is from 0 to 255.
(Optional) Specifies the interval in seconds, between the hello packets that the
router sends on an interface. The valid setting is 1-65535.
(Optional) Specifies the interval in seconds, during which no packets are
received and after which a neighbor is regarded as off-line. The valid setting is 1-
65535.
(Optional) The interval the router waits before it transmits a packet. The valid
setting is 1-65535.
(Optional) The interval the router waits before it retransmits a packet. The valid
setting is 1-65535.
No OSPF virtual link is configured.
hello-interval SECONDS: 10 seconds
dead-interval SECONDS: 40 seconds
transmit-delay SECONDS: 1 second
retransmit-interval SECONDS: 5 seconds
Router configuration
All areas in an OSPF autonomous system must be physically connected to the
backbone area (area 0). In some cases where this physical connection is not
possible, use a virtual link to connect to the backbone through a non-backbone
area. As mentioned, use virtual links to connect two parts of a partitioned
backbone through a non-backbone area. The area through which the virtual link
is configured, is known as a transit area, and it must have the full routing
information. The transit area cannot be a stub area.
