Description: The value of vRtrMplsGenLeastFillReoptiThd specifies in percentage the least reoptimization threshold parameter used in the least-fill path selection process.

During a timer-based re-signaling of an LSP path which has vRtrMplsLspLeastFill enabled, CSPF will first update the least-available bandwidth figure for the current path of this LSP. It then applies the least-fill path selection method to select a new path for this LSP. If the new computed path has the same cost as the current path, it will compare the least-available bandwidth figures of the two paths and if the difference exceeds vRtrMplsGenLeastFillReoptiThd, a trap will be generated to indicate that a better least-fill path is available for this LSP.
