Transparent Interconnection of Lots of Links (TRILL):
Clarifications, Corrections, and Updates
Abstract
Since the publication of the TRILL (Transparent Interconnection of
Lots of Links) base protocol in 2011, active development and
deployment of TRILL have revealed errata in RFC 6325 and areas that
could use clarifications or updates. RFC 7177, RFC 7357, and an
intended replacement of RFC 6439 provide clarifications and updates
with respect to adjacency, the TRILL ESADI (End Station Address
Distribution Information) protocol, and Appointed Forwarders,
respectively. This document provides other known clarifications,
corrections, and updates. It obsoletes RFC 7180 (the previous "TRILL
clarifications, corrections, and updates" RFC), and it updates RFCs
6325, 7177, and 7179.
