disable-incremental-spf-opt

Disables incremental full SPF optimizations for Intermediate System-to-Intermediate System (IS-IS).

Syntax

no disable-incremental-spf-opt

Command Default

Disabled.

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".

If you disable the partial SPF optimizations using the disable-partial-spf-opt command, IS-IS automatically disables the incremental SPF optimizations and always runs full SPF. However, if you disable incremental SPF optimizations using this command, IS-IS does not disable partial optimizations.

The no form of the command restores incremental SPF optimizations for IS-IS.

Examples

The following example disables incremental SPF optimizations for IS-IS.

device# configure terminal
device(config)# router isis
device(config-isis-router)# disable-incremental-spf-opt

The following example restores incremental SPF optimizations for IS-IS.

device# configure terminal
device(config)# router isis
device(config-isis-router)# no disable-incremental-spf-opt
