Technical Summary
This document describes extensions to the Intermediate System to
Intermediate System (IS-IS) protocol to support Traffic Engineering
(TE). This document extends the IS-IS protocol by specifying new
information that an Intermediate System (router) can place in Link
State Protocol (LSP) Data Units. This information describes
additional details regarding the state of the network that are useful
for traffic engineering computations.
This document replaces RFC3784.
Working Group Summary
This is part of a series of seven IS-IS documents that was
originally published as informational for historic reasons, and
is being upgraded to proposed standard. There is broad consensus
in the WG for this upgrade.
Document Quality
These extensions have been widely deployed in multivendor
networks.
Personnel
Chris Hopps and Dave Ward have been jointly acting as shepherds
for this series of seven documents. Ross Callon is responsible AD.
RFC Editor Note
Please replace section 6 (Security Considerations) as follows:
OLD
6. Security Considerations
This document raises no new security issues for IS-IS.
NEW
6. Security Considerations
This document raises no new security issues for IS-IS; for
general security considerations for IS-IS see [RFC3567bis].
Please add the following informative reference in section 8.2:
[RFC3567bis] Li, T. and R. Atkinson, "Intermediate System to
Intermediate System (IS-IS) Cryptographic Authentication",
work in progress.
Please update all references to [RFC2966] to instead reference
draft-ietf-isis-rfc2966bis.
Also please note that draft-ietf-isis-rfc2966bis has been
approved, and [RFC3567bis] is within a few days of being
approved, and it probably would be preferable to hold
this document until you can publish all three (actually all
seven of the related IS-IS documents being progressed) at
the same time.

this. Thanks.
