DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enables OSPF routing for the specified routing process
and places the router in router configuration mode.
router ospf process-name
Example:
Step 2
The process-name argument is any
alphanumeric string no longer than 40
characters.
Note
RP/0/RP0/CPU0:router(config)# router ospf 1
Configures a router ID for the OSPF process.
router-id { router-id }
Step 3
Example:
We recommend using a stable IPv4 address as
the router ID.
Note
RP/0/RP0/CPU0:router(config-ospf)# router id
10.10.10.100
(Optional) Requests notification of neighbor changes.log adjacency changes [ detail | disable ]
Step 4
Example:
• By default, this feature is enabled.
RP/0/RP0/CPU0:router(config-ospf-ar-if)# log
adjacency changes detail
• 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.
(Optional) Configures NSF OSPF protocol.nsf { cisco [ enforce global ] | ietf [ helper disable ]}
Step 5
Example:
The example enables graceful restart.
RP/0/RP0/CPU0:router(config-ospf)# nsf ietf
(Optional) Sets SPF throttling timers.
timers throttle spf spf-start spf-hold spf-max-wait
Example:
Step 6
RP/0/RP0/CPU0:router(config-ospf)# timers throttle
spf 500 500 10000
Enters area configuration mode.
area area-id
Step 7
Example:
The area-id argument can be entered in dotted-decimal
or IPv4 address notation, such as area 1000 or
RP/0/RP0/CPU0:router(config-ospf)# area 1
area 0.0.3.232. However, you must choose one form or
