Step 2
•
router ospf process-name
or
•
router ospfv3 process-name
Enables OSPFv3 routing for the specified routing process and
places the router in router ospfv3 configuration mode.
Example:
RP/0/RSP0/CPU0:router(config)# router ospf 1
The process-name argument is any alphanumeric
string no longer than 40 characters.
Note
or
RP/0/RSP0/CPU0:router(config)# router ospfv3 1
Configures a router ID for the OSPF process.
router-id { router-id }
Step 3
Example:
RP/0/RSP0/CPU0:router(config-ospf)# router-id
192.168.4.3
We recommend using a stable IP address as the router
ID.
Note
Enters area configuration mode and configures an area for the
OSPF process.
area area-id
Example:
RP/0/RSP0/CPU0:router(config-ospf)# area 0
Step 4
•
Backbone areas have an area ID of 0.
•
Nonbackbone areas have a nonzero area ID.
•
The area-id argument can be entered in dotted-decimal
or IPv4 address notation, such as area 1000 or
area 0.0.3.232. However, you must choose one form or
the other for an area. We recommend using the IPv4
address notation.
Enters interface configuration mode and associates one or
more interfaces for the area configured in Step 4.
interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)# interface
GigabitEthernet 0/1/0/3
Step 5
—
Repeat Step 5 for each interface that uses OSPF.
Step 6
(Optional) Requests notification of neighbor changes.log adjacency changes [ detail ] [ enable | disable ]
Step 7
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar-if)# log
adjacency changes detail
•
By default, this feature is enabled.
•
The messages generated by neighbor changes are
considered notifications, which are categorized as
severity Level 5 in the logging console command. The
logging console command controls which severity level
of messages are sent to the console. By default, all
severity level messages are sent.
