COMMAND LINE INTERFACE

timers spf

Use this command to configure the hold time between making two consecutive shortest path first (SPF) calculations. Use the no form to restore the default value.

Syntax

timers spf spf-holdtime no timers spf

spf-holdtime- Minimum time between two consecutive SPF calculations. (Range: 0-65535 seconds)

Command Mode

Router Configuration

Default Setting

10 seconds

Command Usage

•Setting the SPF holdtime to 0 means that there is no delay between consecutive calculations.

•Using a low value allows the router to switch to a new path faster, but uses more CPU processing time.

Example

Console(config-router)#timers spf 20

Console(config-router)#

4-250
