The BGP Graceful Restart mechanism defined in RFC 4724 limits the
usage of BGP Graceful Restart to BGP messages other than BGP
NOTIFICATION messages. 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 subcode for
BGP Cease NOTIFICATION messages; this new subcode requests a full
session restart instead of a Graceful Restart.
This document is a product of the Inter-Domain Routing Working Group of the
IETF.
This is now a Proposed Standard.
