The IESG has approved the Internet-Draft 'Use of Interior Gateway
Protocol Metric as a second MPLS Traffic Engineering Metric'
<draft-ietf-tewg-te-metric-igp-02.txt> as a BCP. This document is the
product of the Internet Traffic Engineering Working Group. The IESG
contact persons are Scott Bradner and Bert Wijnen.
Technical Summary
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.
Working Group Summary
Working Group has consensus on this document to be published as
BCP. IETF Last Call did not raise any comments.
Protocol Quality
This document was reviewed for the IESG by Bert Wijnen.
