This draft is a work item of the Internet Traffic Engineering Working Group of the IETF.

	Title		: Use of Interior Gateway Protocol Metric as a second 
                          MPLS Traffic Engineering Metric

This document describes a common practice on how the existing metric 
of Interior Gateway Protocols (IGP) can be used as an alternative 
metric to the Traffic Engineering (TE) metric for Constraint Based 
Routing of MultiProtocol Label Switching (MPLS) Traffic Engineering 
tunnels. This effectively results in the ability to perform 
Constraint Based Routing with optimization of one metric (e.g. link 
bandwidth) for some Traffic Engineering tunnels (e.g. Data Trunks) 
while optimizing another metric (e.g. propagation delay) for some 
other tunnels with different requirements (e.g. Voice Trunks).

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.
