      Transparent Interconnection of Lots of Links (TRILL) over IP
                     draft-mrw-trill-over-ip-03.txt

Abstract

   The Transparent Interconnection of Lots of Links (TRILL) protocol is
   implemented by devices called TRILL Switches or RBridges (Routing
   Bridges).  TRILL supports both point-to-point and multi-access links
   and is designed so that a variety of link protocols can be used
   between TRILL switch ports.  This document standardizes methods for
   encapsulating TRILL in IP(v4 or v6) to provide a unified TRILL
   campus.
