partial-spf-interval

Changes the partial shortest path first (PSPF) interval.

Syntax

partial-spf-interval max-wait initial-wait second-wait

no partial-spf-interval

Parameters

max-wait: Specifies the maximum interval in seconds between SPF recalculations. The range is from 0 through 120 seconds. The default is 5 seconds.
initial-wait: Specifies the initial SPF calculation delay in milliseconds after an LSP change. The range is from 0 through 120000 milliseconds. The default for this variable is value of the max-wait time.
second-wait: Indicates the hold time between the first and second SPF calculation in milliseconds. The range is from 1 through 120000 milliseconds. The default is 5000 milliseconds (5 seconds). The default for this variable is value of the max-wait time.

Modes

IS-IS router configuration mode

Usage Guidelines

IS-IS is supported only on devices based on the DNX chipset family. For a list of such devices, see "Supported Hardware".

The no form of the command restores the defaults.

Examples

The following example specifies that the maximum interval between SPF recalculations is 15 seconds, the initial SPF calculation delay is 10000 milliseconds, and the hold time between the first and second SPF calculation is 15000 milliseconds.

device# configure terminal
device(config)# router isis
device(config-isis-router)# partial-spf-interval 15 10000 15000

The following example restores the default values.

device# configure terminal
device(config)# router isis
device(config-isis-router)# no partial-spf-interval
