or
router ospfv3
process-name
Example:
RP/0/RP0/CPU0:router(config)# router ospf 1
or
RP/0/RP0/CPU0:router(config)# router ospfv3 1
Enables OSPF routing for the specified routing process, and
places the router in router configuration mode.

interface-instance
}
Example:
RP/0/RP0/CPU0:router(config-ospf)# router-id
192.168.4.3
Configures a router ID for the OSPF process.
Note We recommend using a stable IP address as the
router ID.
Step 4
area
area-id
Example:
RP/0/RP0/CPU0:router(config-ospf)# area 1
Enters area configuration mode and configures a
nonbackbone area for the OSPF process.
• The area-id argument can be entered in dotted-decimal

area 0.0.3.232. However, you must choose one form or
the other for an area. We recommend using the IPv4
address notation.
