    abstract =  {The current BGP Graceful Restart mechanism limits the usage of BGP Graceful Restart to BGP protocol messages other than a BGP NOTIFICATION message. This document defines an extension to the BGP Graceful Restart that permits the Graceful Restart procedures to be performed when the BGP speaker receives a BGP NOTIFICATION Message. This document also defines a new BGP NOTIFICATION Cease Error subcode to prevent BGP speakers supporting the extension defined in this document from performing a Graceful Restart.},
