    abstract =  {This document describes extensions to the ISIS Traffic Engineering (ISIS-TE) mechanisms 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.},
