A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Internet Traffic Engineering Working Group of the IETF.

	Title		: Use of IGP Metric as a second TE Metric
	Author(s)	: F. Le Faucheur et al.
	Filename	: draft-lefaucheur-te-metric-igp-01.txt
	Pages		: 7
	Date		: 13-Nov-01
	
This draft describes a common practice on how the existing IGP 
Metric can be used as an alternative metric to the TE Metric for 
Constraint Based Routing of MPLS TE Tunnels. This effectively 
results in the ability to perform Constraint Based Routing with 
optimization of one metric (e.g. link bandwidth) for some TE Tunnels 
(e.g. Data Trunks) while optimizing another metric (e.g. propagation 
delay) for some other TE Tunnels with different requirements (e.g. 
Voice Trunks). 
No protocol extensions or modifications are required. This text 
documents current router implementations and deployment practices.

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.

implementation to automatically retrieve the ASCII version of the
