Transparent Interconnection of Lots of Links : Appointed Forwarders
RFC 8139, “Transparent Interconnection of Lots of Links : Appointed Forwarders”, is a Proposed Standard document published in June 2017 by D. Eastlake 3rd, Y. Li, M. Umair, A. Banerjee, F. Hu. It updates RFC 6325, RFC 7177. It obsoletes RFC 6439. The canonical text is published by the RFC Editor.
Abstract
TRILL (Transparent Interconnection of Lots of Links) supports multi-access LAN (Local Area Network) links where a single link can have multiple end stations and TRILL switches attached. Where multiple TRILL switches are attached to a link, native traffic to and from end stations on that link is handled by a subset of those TRILL switches called "Appointed Forwarders" as originally specified in RFC 6325, with the intent that native traffic in each VLAN be handled by at most one TRILL switch. This document clarifies and updates the Appointed Forwarder mechanism. It updates RFCs 6325 and 7177 and obsoletes RFC 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.
