Controlling The Frequency That The Same Lsa Is Originated Or Accepted For Ospf - Cisco NCS 6000 Series Configuration Manual

Implementing OSPF
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:
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
Command or Action
Step 1
configure
Step 2 Do one of the following:
• router ospf process-name
• router ospfv3 process-name
Example:
RP/0/RP0/CPU0:router:router(config)# router ospf
1
or
RP/0/RP0/CPU0:router(config)# router ospfv3 1
Step 3 router-id { router-id }
Example:
RP/0/RP0/CPU0:router(config-ospf)# router-id
192.168.4.3
Step 4 Perform Step 5 or Step 6 or both to control the frequency
that the same LSA is originated or accepted.
Step 5
timers lsa refresh seconds
Example:
• router ospf process-name
• router ospfv3 process-name

Controlling the Frequency That the Same LSA Is Originated or Accepted for OSPF

Purpose
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
Note
alphanumeric string no longer than 40 characters.
Configures a router ID for the OSPF process.
We recommend using a stable IP address as the
Note
router ID.
