This document discusses BGP shutdown communication. It provides examples of using OpenBGPD and JunOS to shutdown BGP neighbor sessions and send shutdown messages. Various BGP implementations that support sending shutdown messages are listed, including OpenBGPD, GoBGP, Pmacct, ExaBGP, and projects at the IETF. It also mentions that UTF-8 encoding works for shutdown messages.
