Configuring Fspf Gr; Displaying And Maintaining Fc Routing And Forwarding - HP 6125XLG Configuration Manual

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
