Description This command enables the RSVP Graceful Restart Helper feature.
The RSVP-TE Graceful Restart helper mode allows the SR OS based system (the helper node) to
provide another router that has requested it (the restarting node) a grace period, during which the
system will continue to use RSVP sessions to neighbors requesting the grace period. This is typically
used when another router is rebooting its control plane but its forwarding plane is expected to
continue to forward traffic based on the previously available Path and Resv states.
The user can enable Graceful Restart helper on each RSVP interface separately. When the GR helper
feature is enabled on an RSVP interface, the node starts inserting a new Restart_Cap Object in the
Hello packets to its neighbor. The restarting node does the same and indicates to the helper node the
desired Restart Time and Recovery Time.
