DETAILED STEPS
Step 1 configure
Step 2 Do one of the following:
• router ospf process-name
• 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.
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 timers throttle spf spf-start spf-hold spf-max-wait
Example:
RP/0/RP0/CPU0:router(config-ospf)# timers throttle spf 10 4800 90000
Sets SPF throttling timers.
Step 5 area area-id
Example:
RP/0/RP0/CPU0:router(config-ospf)# area 0
Enters area configuration mode and configures a backbone area.
• 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.
Step 6 interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-ospf-ar)# interface TenGigE 0/0/0/0
