DETAILED STEPS
Step 1 configure
Step 2 router ospf process-name
Example:
RP/0/RP0/CPU0:router(config)# router ospf 1
Enables OSPF routing for the specified routing process and places the router in router configuration mode.
The process-name argument is any alphanumeric string no longer than 40 characters.
Note
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.
We recommend using a stable IPv4 address as the router ID.
Note
Step 4 Do one of the following:
• nsf cisco
• nsf cisco enforce global
Example:
RP/0/RP0/CPU0:router(config-ospf)# nsf cisco enforce global
Enables Cisco NSF operations for the OSPF process.
• Use the nsf cisco command without the optional enforce and global keywords to abort the NSF restart mechanism
on the interfaces of detected non-NSF neighbors and allow NSF neighbors to function properly.
• Use the nsf cisco command with the optional enforce and global keywords if the router is expected to perform
NSF during restart. However, if non-NSF neighbors are detected, NSF restart is canceled for the entire OSPF process.
Step 5 nsf interval seconds
Example:
RP/0/RP0/CPU0:router(config-ospf)# nsf interval 120
Sets the minimum time between NSF restart attempts.
