Graceful BGP Session Shutdown
You can minimize the traffic lost by Graceful Shutdown when you shut down a BGP session, such as for planned maintenance. You can set the LocalPref attribute in our network to 0 by advertising a route with a community of 65535:0.
This feature is available for all our BGP connections. (BGP customers, transits, peers)
If you need more information about Graceful BGP Session Shutdown, please refer to RFC8326.
