Disabling incremental SPF optimizations

IS-IS is configured to use an incremental shortcut LSP SPF optimization algorithm by default. This task disables incremental shortcut LSP SPF optimization.

Procedure

  1. Enter the configure terminal command to access global configuration mode.
    device# configure terminal
  2. Enter the router isis command to enter IS-IS router configuration mode and enable IS-IS on the device.
    device(config)# router isis
    
  3. Enter the disable-inc-stct-spf-opt command to disable incremental shortcut LSP SPF optimization.
    device(config-isis-router)# disable-inc-stct-spf-opt
    

Example

The following example disables incremental shortcut LSP SPF optimization.

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