1. Introduction

   This draft describes how data center network can benefit from
   non-RBridge nodes performing TRILL encapsulation with
   assistance from directory service.

   [RFC7067] describes the framework for RBridge edge to get
   MAC&VLAN<->RBridgeEdge mapping from a directory service in
   data center environment instead of flooding unknown DAs across
   TRILL domain. When directory is used, any node, even a non-
   RBridge node, can perform the TRILL encapsulation. This draft
   is to describe the benefits and the scheme of non-RBridge
   nodes performing TRILL encapsulation.
