The RSVP-TE specification, "RSVP-TE: Extensions to RSVP for LSP
Tunnels" (RFC 3209) and GMPLS extensions to RSVP-TE, "Generalized
Multi-Protocol Label Switching (GMPLS) Signaling Resource ReserVation
Protocol-Traffic Engineering (RSVP-TE) Extensions" (RFC 3473) allow
abstract nodes and resources to be explicitly included in a path
setup, but not to be explicitly excluded.
In some networks where precise explicit paths are not computed at the
head end it may be useful to specify and signal abstract nodes and
resources that are to be explicitly excluded from routes. These
exclusions may apply to the whole path, or to parts of a path between
two abstract nodes specified in an explicit path. How Shared Risk
Link Groups (SLRGs) can be excluded is also specified in this
This document specifies ways to communicate route exclusions during
path setup using RSVP-TE.

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
