Transparent Interconnection of Lots of Links : Adjacency
RFC 7177, “Transparent Interconnection of Lots of Links : Adjacency”, is a Proposed Standard document published in May 2014 by D. Eastlake 3rd, R. Perlman, A. Ghanwani, H. Yang, V. Manral. It updates RFC 6325. It obsoletes RFC 6327. It has since been updated by RFC 7780, RFC 8139, RFC 8249, RFC 8377, RFC 8564. The canonical text is published by the RFC Editor.
Abstract
The IETF Transparent Interconnection of Lots of Links (TRILL) protocol supports arbitrary link technologies between TRILL switches, including point-to-point links and multi-access Local Area Network (LAN) links that can have multiple TRILL switches and end stations attached. TRILL uses Intermediate System to Intermediate System (IS-IS) routing. This document specifies the establishment, reporting, and termination of IS-IS adjacencies between TRILL switches, also known as RBridges (Routing Bridges). It also concerns four other link-local aspects of TRILL: Designated RBridge (DRB) selection, MTU (Maximum Transmission Unit) testing, pseudonode creation, and BFD (Bidirectional Forwarding Detection) session bootstrapping in connection with adjacency. State diagrams are included where appropriate. This document obsoletes RFC 6327 and updates RFC 6325.
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.
