The ability to compute an optimal path for setting up Traffic
engineering Label Switched Paths spanning multiple autonomous
systems managed by different operators has been a key requirement in
MPLS and GMPLS networks. This document specifies a method of
computing inter-AS paths consisting of a list of ASes to be
traversed and a list of FA-LSPs to be traversed in each AS. The
method described here uses BGP running in the PCEs of each AS to
distribute the inter-AS connectivity information and the FA-LSPs in
each AS to its neighbors to facilitate the construction of an inter-
AS topology graph which can be used for computing inter-AS paths.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
