Transparent Interconnection of Lots of Links (TRILL) Use of IS-IS
Abstract
The IETF has standardized the Transparent Interconnection of Lots of
Links (TRILL) protocol, which provides transparent Layer 2 forwarding
using encapsulation with a hop count and IS-IS link state routing.
This document specifies the data formats and code points for the
IS-IS extensions to support TRILL.
