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
   specifies a mechanism to transmit a short freeform UTF-8 [RFC3629]
   message as part of a Cease NOTIFICATION message [RFC4486] to inform
   the peer why the BGP session is being shutdown or reset.
