BGP Capabilities are carried in this field and may foreseeably exceed 255 octets in the future, leading to concern about this limitation. In this document we update RFC 4271 by extending the BGP OPEN length field in a backward-compatible manner. The Parameter Length field of individual Optional Parameters is similarly extended.}, }
