Some applications are highly sensitive to traffic loss lasting tens of milliseconds or more, yet typical router convergence after a link or node failure can take several hundred milliseconds. To minimize this loss, the router must rapidly activate a precomputed alternate repair path for all prefixes affected by the failure. IP FRR enables this by precomputing the repair path, allowing the router to switch to it immediately upon failure without waiting for full convergence.
