1.  Introduction

   The Administrative Shutdown Communication [RFC8203] is a simple
   mechanism to transit 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.

   Feedback from operators based in regions which predominantly use
   multibyte character sets, showed that messages similar in meaning to
   what can be send in other languages in using single-byte encoding
   failed to fit within the Length constraints as specified by
   [RFC8203].  For example, the phrase: 'Planned work to add switch to
   stack.  Completion time - 30 minutes' has length 65 bytes.  Its
   translation in Russian
   'Плановые
   работы по д&#10
   86;бавлению к&#
   1086;ммутатора
   в стек.
   Время заве&#108
   8;шения - 30
   минут' (See PDF for non-ASCII character
   string) has length 139 bytes.

   This document extends the length of the Administrative Shutdown
   Communication to 255 octets.

2.  Changes to RFC 8203

   This section updates [RFC8203] to specify the maximum length of an
   Administrative Shutdown Communication.

   The following paragraph replaces the Length definition in Section 2
   (Shutdown Communication):

      Length:  this 8-bit field represents the length of the Shutdown
         Communication field in octets.  When the length value is zero,
         no Shutdown Communication field follows.

   The following paragraph replaces the second paragraph of Section 5
   (Security Considerations):
