1. Introduction
This draft describes how data center network can benefit from non-
RBridge nodes performing TRILL encapsulation with assistance from
directory service.
[RBridge-directory] 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 non-RBridge node, can
