ipv6 router ospf tag
area
This command binds an OSPF area to the selected interface and process.
Use the no form to remove the specified area from an interface.
[no] ipv6 router ospf tag process-name area area-id
[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 used to distinguish between
multiple routing instances configured on the local router.
(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)

◆ 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 this 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.
E XAMPLE
This example assigns area 0.0.0.1 to the currently selected interface under
routing process “1.”
