Configuring OSPF Shortest Path First Throttling
This task explains how to configure SPF scheduling in millisecond intervals and potentially delay SPF
calculations during times of network instability. This task is optional.
Prerequisites
See the “OSPF Shortest Path First Throttling” section on page RC-139 for information about OSPF SPF
throttling.
SUMMARY STEPS
1. configure
2. router ospf process-name
or
router ospfv3 process-name
3. router-id {ipv4-address | interface-type interface-instance}
4. timers throttle spf spf-start spf-hold spf-max-wait
5. area area-id
6. interface type instance
7. end
or
commit
8. show ospf [process-name]
or
show ospfv3 [process-name]
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.
