The specification of the IP Flow Information Export (IPFIX) Protocol [RFC7011] defines an IPFIX Message length of 16 bits. As new Information Elements (IEs) are introduced in IPFIX to export long information, such as the BGP community information [I-D.ietf-opsawg-ipfix-bgp-community], an IPFIX Message no longer has sufficient space to fit all the information of a specific flow. This document updates the IPFIX specification by extending the IPFIX Message length from 16 bits to 32 bits. For backwards compatibility, a new version of IPFIX (i.e., 11) is introduced to support the 32-bit Message length.
