timers lsa-arrival (OSPF)

To set the minimum interval in which the software accepts the same link-state advertisement (LSA) from Open Shortest Path First (OSPF) neighbors, use the timers lsa-arrival command. To return to the default, use the no form of this command.

timers lsa-arrival milliseconds

no timers lsa-arrival

Syntax Description


Minimum delay (in milliseconds) that must pass between acceptance of the same LSA arriving from neighbors. The range is from 10 to 600,000 milliseconds. The default is 1000 milliseconds.

Command Default

1000 milliseconds

Command Modes

Usage Guidelines

Use the timers lsa arrival command to configure the minimum interval for accepting the same LSA. The same LSA is an LSA instance that contains the same LSA ID number, LSA type, and advertising router ID. If an instance of the same LSA arrives sooner than the interval that is set, the software drops the LSA.

We recommend that you keep the milliseconds value of the timers lsa-arrival command less than or equal to the neighbors' hold-interval value of the timers throttle lsa command.

This command requires the LAN Base Services license.


This example shows how to set the minimum interval for accepting the same LSA at 2000 milliseconds:

switch(config)# router ospf 1
switch(config-router)# timers lsa-arrival 2000
