   "Administrative Shutdown" and "Administrative Reset" subcodes for
   operators to transmit a short freeform message to describe why a BGP
   session was shutdown or reset.  This document updates RFC 4486.

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 offline methods such as 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.

1.1.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in
   BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

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.
