Transparent Interconnection of Lots of Links : Clarifications, Corrections, and Updates
RFC 7180, “Transparent Interconnection of Lots of Links : Clarifications, Corrections, and Updates”, is a Proposed Standard document published in May 2014 by D. Eastlake 3rd, M. Zhang, A. Ghanwani, V. Manral, A. Banerjee. It updates RFC 6325, RFC 6327, RFC 6439. It has been obsoleted by RFC 7780 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
The IETF Transparent Interconnection of Lots of Links (TRILL) protocol provides least-cost pair-wise data forwarding without configuration in multi-hop networks with arbitrary topology and link technology, safe forwarding even during periods of temporary loops, and support for multipathing of both unicast and multicast traffic. TRILL accomplishes this by using Intermediate System to Intermediate System (IS-IS) link-state routing and by encapsulating traffic using a header that includes a hop count. Since publication of the TRILL base protocol in July 2011, active development of TRILL has revealed errata in RFC 6325 and some cases that could use clarifications or updates.
RFCs 6327 and 6439 provide clarifications and updates with respect to adjacency and Appointed Forwarders. This document provides other known clarifications, corrections, and updates to RFCs 6325, 6327, and 6439.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
