This document describes extensions to the ISIS (ISIS) protocol to support Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering (TE) for multiple Autonomous Systems (ASes). It defines ISIS-TE extensions for the flooding of TE information about inter-AS links, which can be used to perform inter- AS TE path computation. No support for flooding information from within one AS to another AS is proposed or defined in this document. This document obsoletes [RFC5316]
