A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Common Control and Measurement Plane Working Group of the IETF.

	Title		: Exclude Routes - Extension to RSVP-TE
	Author(s)	: A. Farrel, et al.
	Filename	: draft-ietf-ccamp-rsvp-te-exclude-route-04.txt
	Pages		: 34

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
   document.

   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.
