1.  Introduction

   It can be troublesome for an operator to correlate a BGP-4 [RFC4271]
   session teardown in the network with a notice that was transmitted
   via off-line methods such email or telephone calls.  This document
   updates [RFC4486] by specifying a mechanism to transmit a short
   freeform UTF-8 [RFC3629] message as part of a Cease NOTIFICATION
   message [RFC4271] to inform the peer why the BGP session is being
   shutdown or reset.

2.  Shutdown Communication

   If a BGP speaker decides to terminate its session with a BGP
   neighbor, and it sends a NOTIFICATION message with the Error Code
   "Cease" and Error Subcode "Administrative Shutdown" or
   "Administrative Reset" [RFC4486], it MAY include an UTF-8 encoded
   string.  The contents of the string are at the operator's discretion.

   The Cease NOTIFICATION message with a Shutdown Communication is
   encoded as below:
