area virtual-link (IPv6 OSPF)
Overview
This command configures a link between a non-backbone area and the backbone,
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.

Parameter
Description
<area-id>
The area-ID of the transit area that the virtual link passes
through. This can be entered in either dotted decimal format or
normal decimal format as shown below.
<A.B.C.D>
OSPF area-ID, expressed in the IPv4
address format
<A.B.C.D>
.
<0-4294967295>
OSPF area-ID expressed as a decimal
number within the range shown.
For example the values dotted decimal 0.0.1.2 and decimal 258
would both define the same area-ID.
<router-id>
The OSPF router ID of the virtual link neighbor.
dead-interval
If no packets are received from a particular neighbor for
dead-interval seconds, the router considers the neighbor router
to be off-line.
Default: 40 seconds
<1-65535>
The number of seconds in the interval.
hello-interval
The interval the router waits before it sends a hello packet.
Default: 10 seconds
<1-65535>
The number of seconds in the interval.
retransmit-
interval
The interval the router waits before it retransmits a packet.
Default: 5 seconds
<1-65535>
The number of seconds in the interval.
