Ballot Text

Technical Summary

   The BGP Graceful Restart mechanism defined in RFC 4724 limits the
   usage of BGP Graceful Restart to BGP protocol messages other than a
   BGP NOTIFICATION message.  This document updates RFC 4724 by defining
   an extension that permits the Graceful Restart procedures to be
   performed when the BGP speaker receives a BGP NOTIFICATION Message or
   the Hold Time expires.  This document also defines a new BGP
   NOTIFICATION Cease Error subcode whose effect is to request a full
   session restart instead of a Graceful Restart.
