The value of vRtrRsvpIfGraceHelper specifies whether graceful restart helper mode is enabled or disabled. When the graceful restart helper mode when enabled, the system will advertise Restart capability object which will allow neighboring router to request for a grace period during which the system will continue to use previously established RSVP session. This is typically used when a neighboring router's control plane restarts but its forwarding plane is expected to continue to forward traffic. The system will advertise Restart capability object with value of the restart, and the recovery times always set to 0.
