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).  No
protocol extensions or modifications are required.  This text
documents current router implementations and deployment practices.
