You can configure a device to function as a Graceful Restart (GR) helper to help a BGP peer with the BGP GR process.
Usage Scenario
When BGP restarts, the peer relationship is re-established, and traffic forwarding is interrupted. To address this issue, enable GR.
GR takes effect only when BGP GR is enabled and a GR-capable BGP session is established between the GR restarter and its peers.
