Abstract

The IETF has standardized the Transparent Interconnection of Lots of Links (TRILL) protocol [RFC6325], which provides a solution for least-cost transparent routing in multi-hop networks with arbitrary topologies and link technologies, using [IS-IS] [RFC6165] [RFC7176] link-state routing and a hop count. TRILL switches are sometimes called RBridges (Routing Bridges).

Abstract

   The IETF has standardized Transparent Interconnection of Lots of    Links (TRILL), a protocol for least-cost transparent frame routing in    multi-hop networks with arbitrary topologies and link technologies,    using link-state routing and a hop count.  The TRILL base protocol    standard supports the labeling of TRILL Data packets with up to 4K    IDs.  However, there are applications that require a larger number of    labels providing configurable isolation of data.  This document    updates RFC 6325 by specifying optional extensions to the TRILL base    protocol to safely accomplish this.  These extensions, called fine-    grained labeling, are primarily intended for use in large data    centers, that is, those with more than 4K users requiring    configurable data isolation from each other.
