DETAILED STEPS
Command or Action Purpose
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters global configuration mode.
Step 2
router ospf process-name
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.
or
Enables OSPFv3 routing for the specified routing process
and places the router in router ospfv3 configuration mode.
Note The process-name argument is any alphanumeric
string no longer than 40 characters.
Step 3
router-id { router-id }
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 IPv4 address as the
