This object sets the maximum interval, in seconds, between generated LSPs by this IS-IS instance, following resettingTimer behavior, and must stay smaller than csIsisSysMaxLSPLifetime and larger than csIsisSysMinL1LSPGenInt. Administrators tune it to control how often this router refreshes its own link-state information even absent a topology change. For example, an engineer lowers csIsisSysMaxLSPGenInt to force more frequent LSP regeneration on a link known to have intermittent LSP loss, ensuring fresher topology information circulates despite the loss.
