Description: Set this object to 'true' to minimize the delay before triggering a routing calculation that includes any relevant circuit change. This means a change to the local neighbors (including pseudonodes), or to the reachable addresses received from the I3 stub.

There are two aspects to minimizing the delay.

- IS-IS overrides the setting of the prvtIsisSysLevelMinLSPGenInt object when such a change occurs, and usually regenerates the local LSP(s) immediately. The only exception is when IS-IS is performing restart procedures as defined in RFC3847. This RFC specifies when IS-IS can update the local LSP during a restart.

- IS-IS overrides all of the objects that affect the scheduling of routing calculations, with the exception of the prvtIsisSysCalcThrshRestartLimit object. It ensures that a routing calculation including the updated LSPs takes place as soon as possible. It abandons an existing route calculation if necessary, unless more than prvtIsisSysCalcThrshRestartLimit successive calculations would have been interrupted.
