Configuring FSPF GR

FSPF Graceful Restart (GR) enables 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 device where a protocol restart or active/standby switchover occurs
GR Helper—The GR Restarter's neighboring device that assists in the GR process
•
Configuring the GR Restarter
