AREA VIRTUAL LINK

area virtual-link

Overview This command configures a link between two backbone areas that are physically
separated through other non-backbone 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 variant of this command removes the virtual link.
