This document describes extensions to the Intermediate System to
Intermediate System (IS-IS) protocol to support Multiprotocol Label
Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering
(TE) for multiple Autonomous Systems (ASes). It defines IS-IS
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 builds on RFC 5316 by adding support for IPv6-only
operation.
This document obsoletes RFC 5316.
This document is a product of the Link State Routing Working Group of the IETF.
This is now a Proposed Standard.
