Graceful BGP Session Shutdown

Authors: Pierre Francois, Bruno Decraene, Cristel Pelsser, Keyur Patel, Clarence Filsfils

Abstract: This document standardizes a new well-known BGP community, GRACEFUL\_SHUTDOWN, to signal the graceful shutdown of paths. This document also describes operational procedures that use this well-known community to reduce the amount of traffic lost when BGP peering sessions are about to be shut down deliberately, e.g., for planned maintenance.
