DETAILED STEPS
Command or Action
Step 1
configure
Step 2 router ospf process-name
Example:
RP/0/RSP0/CPU0:router(config)# router ospf 1
Step 3 router-id { router-id }

10.10.10.100
Step 4
log adjacency changes [ detail | disable ]
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar-if)# log
adjacency changes detail
Step 5 nsf { cisco [ enforce global ] | ietf [ helper disable
]}
Example:
RP/0/RSP0/CPU0:router(config-ospf)# nsf ietf
Step 6

Purpose
Enables OSPF routing for the specified routing process and
places the router in router configuration mode.
The process-name argument is any alphanumeric
Note
string no longer than 40 characters.
Configures a router ID for the OSPF process.
We recommend using a stable IPv4 address as the
Note
router ID.
(Optional) Requests notification of neighbor changes.
• 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.
(Optional) Configures NSF OSPF protocol.
The example enables graceful restart.
(Optional) Sets SPF throttling timers.
Enters area configuration mode.
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 to the area.
