Fspf Graceful-Restart Helper - HP 6127XLG Blade Series Command Reference Manual

Usage guidelines

FSPF Graceful Restart (GR) ensures nonstop forwarding of traffic by backing up FSPF configuration
information during a protocol restart (for example, the FSPF process restart triggered by the process
command) or active/standby switchover.
GR involves the following roles:
• GR restarter—GR-capable switch where a protocol restart or active/standby switchover occurs.
GR helper—The GR restarter's neighboring switch that assists in the GR process.
