Abstract

   This document discusses how Ethernet VPN (E-VPN) technology is used
   to interconnect TRILL [TRILL] networks over an MPLS/IP network, with
   two key characteristics: C-MAC address transparency on the hand-off
   point and control-plane isolation among the interconnected TRILL
   networks.
