Abstract

   The IETF TRILL (Transparent Interconnection of Lots of Links)
   protocol provides loop free connectivity to Local Area Network (LAN)
   via choice of an Appoint Forwarder (AF) for a set of VLANs and to end
   node via point-to-point link.  The active-active access, as an
   extension access of legacy network or end-device to TRILL campus has
   not been specified.  This document gives the concept of Virtual
   RBridge(RBv), and based on it, specifies the active-active access of
   a legacy network or an end node via a switch that multi-homes to
   TRILL campus.
