Controlling the Frequency That the Same LSA Is Originated or Accepted for
OSPF
This task explains how to tune the convergence time of OSPF routes in the routing table when many LSAs
need to be flooded in a very short time interval.
SUMMARY STEPS
1. configure
2. Do one of the following:
• router ospf process-name
• router ospfv3 process-name
3. router-id { router-id }
4. Perform Step 5 or Step 6 or both to control the frequency that the same LSA is originated or accepted.
5. timers lsa refresh seconds
6. timers lsa min-arrival seconds
7. timers lsa group-pacing seconds
8. commit
DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enables OSPF routing for the specified routing process and
places the router in router configuration mode.
Do one of the following:
Step 2
• router ospf process-name
or
• router ospfv3 process-name
Enables OSPFv3 routing for the specified routing process
and places the router in router ospfv3 configuration mode.
Example:
RP/0/RP0/CPU0:router:router(config)# router ospf
1
The process-name argument is any
alphanumeric string no longer than 40 characters.
Note
or
RP/0/RP0/CPU0:router(config)# router ospfv3 1
Configures a router ID for the OSPF process.
router-id { router-id }
Step 3
Example:
We recommend using a stable IP address as the
router ID.
Note
RP/0/RP0/CPU0:router(config-ospf)# router-id

—Perform Step 5 or Step 6 or both to control the frequency
that the same LSA is originated or accepted.
Step 4
Sets how often self-originated LSAs should be refreshed,
in seconds.
