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.
