The IETF Transparent Interconnection of Lots of Links (TRILL) protocol [RFC6325] [RFC7177] provides transparent forwarding in multi-hop networks with arbitrary topology and link technologies using a header with a hop count and link-state routing. TRILL provides optimal pair-wise forwarding without configuration, safe forwarding even during periods of temporary loops, and support for multipathing of both unicast and multicast traffic. Intermediate Systems (ISs) implementing TRILL are called Routing Bridges (RBridges) or TRILL Switches.

    Transparent Interconnection of Lots of Links (TRILL) Use of IS-IS


   The IETF Transparent Interconnection of Lots of Links (TRILL)    protocol provides optimal pair-wise data frame forwarding without    configuration in multi-hop networks with arbitrary topology and link    technology; it also provides support for multipathing of both unicast    and multicast traffic.  This document specifies the data formats and    code points for the IS-IS extensions to support TRILL.  These data    formats and code points may also be used by technologies other than    TRILL.  This document obsoletes RFC 6326.
