Technical Summary
The IETF TRILL (Transparent Interconnection of Lots of Links)
protocol provides optimal pair-wise data frame forwarding without
configuration in multi-hop networks with arbitrary topology and link
technology, and support for multipathing of both unicast and
multicast traffic.
This document, in conjunction with RFC 6165, specifies the data
formats and code points for the IS-IS [ISO-10589] extensions to
support TRILL. It obsoletes RFC 6326, which corresponded to the
base TRILL protocol as the TRILL Working Group passed it up to the
IESG in 2009. There has been substantial development of TRILL since
them. The changes from RFC 6326 are briefly summarized in the
Introduction and a full list is given in Section 7.
Working Group Summary:
The need for an IPR disclosure was found after the first Working
Group Last Call resulting in a second Working Group Last Call. As a
non-controversial update extending a previous RFC, there was
relatively little discussion.
Owing to some fumbles by the ISIS chairs (honeymoon, NomCom,
hospitalisation) the publication request for this document got
delayed for a long time. This has nothing to do with the quality of the
document and we are trying to play catch-up now.
Document Quality:
The document is of good quality. The vast majority of the code
points and code points specified in this document are in use in
shipping TRILL or similar control plane code from multiple
equipment manufacturers. The predecessor document RFC 6326 was
thoroughly review by Mike Shand and this revision is based on
RFC 6326 incorporating the results of that review.
The document is on the telechat agenda on the day after the last call
ends. A very minor revision is expected to fix a few nits, but currently
no issues of substance have been raised. If a more significant
revision is needed, the document will be moved to a later telechat.
