ipv6 router ospf
area
This command binds an OSPF area to the selected interface. Use the no
form to remove an OSPF area, disable an OSPF process, or remove an
instance identifier from an interface.
SYNTAX
[no] ipv6 router ospf area area-id [tag process-name |
instance-id instance-id]
area-id - Area to bind to the current Layer 3 interface. An OSPF
area identifies a group of routers that share common routing
information. The area ID can be in the form of an IPv4 address or
as a four octet unsigned integer ranging from 0-4294967295.
process-name - A process name must be entered when configuring
multiple routing instances. (Range: Alphanumeric string up to 16
characters)
instance-id - Identifies a specific OSPFv3 routing process on the
link-local network segment attached to this interface.
(Range: 0-255)

COMMAND USAGE
◆ An area ID uniquely defines an OSPF broadcast area. The area ID
0.0.0.0 indicates the OSPF backbone for an autonomous system. Each
router must be connected to the backbone via a direct connection or a
virtual link.
◆ Set the area ID to the same value for all routers on a network segment.
◆ The process-name is only used on the local router to distinguish
between different routing processes (and must be configured with the
router ipv6 ospf command before using it in the ipv6 router ospf area
command).
◆ The instance-id is used on the link-local network segment to distinguish
between different routing processes running on the same link, and
allows routers participating in a common routing process to form
adjacencies and exchange routing information.
◆ The backbone (area 0.0.0.0) must be created before any other area.
EXAMPLE
This example creates the backbone 0.0.0.0.
Console(config)#router ipv6 ospf tag 0
