Disables partial SPF optimizations for Intermediate System-to-Intermediate System (IS-IS).
Disabled.
IS-IS router configuration mode
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 this command, IS-IS automatically disables the incremental SPF optimizations and always runs full SPF. However, if you disable incremental SPF optimizations using the disable-incremental-spf-opt command, IS-IS does not disable partial optimizations.
The no form of the command restores partial SPF optimizations for IS-IS.
The following example disables partial SPF optimizations for IS-IS.
device# configure terminal device(config)# router isis device(config-isis-router)# disable-partial-spf-opt
The following example restores partial SPF optimizations for IS-IS.
device# configure terminal device(config)# router isis device(config-isis-router)# no disable-partial-spf-opt
