Reference Guide

• Each time a topology change occurs, the SPF calculation is delayed for double the congured hold time up to
maximum wait time.
• If no topology change occurs, an SPF calculation is performed and the hold timer is reset to its congured
value.
If you do not specify a start-time, hold-time or max-wait value, the default values are used. The no version of this
command removes the congured SPF timers and disables SPF throttling in an OSPF instance.

OS10(config)# router ospf 100

timers throttle lsa all
Congures the LSA transmit intervals.
Syntax
timers lsa all [start-interval | hold-interval | max-interval]
Parameters
• start-interval — Sets the minimum interval between initial sending and re-sending the same LSA in
milliseconds (0 to 600,000).
• hold-interval — Sets the next interval to send the same LSA in milliseconds. This is the time between
sending the same LSA after the start-interval has been attempted (1 to 600,000).
•
max-interval — Sets the maximum amount of time the system waits before sending the LSA in
milliseconds (1 to 600,000).
.
Default
• start-interval — 0 milliseconds
• hold-interval — 5000 milliseconds
• max-interval — 5000 milliseconds
Command Mode ROUTER-OSPF
Usage Information The no version of this command removes the LSA transmit timer.
Example
OS10(config)# router ospf 10
OS10(conf-router-ospf-10)# timers throttle lsa all 100 300 1000
