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
Console(config-router)#router-id 192.168.0.2
Console(config-router)#exit
Console(config)#interface vlan 1
Console(config-if)#ipv6 router ospf area 0 tag 0 instance-id 0
