Area Virtual-Link - Allied Telesis SwitchBlade x908 Series Software Reference Manual

OSPF Commands

area virtual-link

This command configures a link between two backbone areas that are physically separated
through other nonbackbone areas.
In OSPF, all non-backbone areas must be connected to a backbone area. If the connection to
the backbone is lost, the virtual link repairs the connection.
The no form removes the virtual link.

Description
The area ID of the transit area that the virtual link passes through. Use
one of the following formats: This can be entered in either dotted
decimal format or normal decimal format.

For example the values dotted decimal 0.0.1.2 and decimal 258 would
both define the same area ID.
The OSPF router ID of the virtual link neighbor.
