                                 TRILL:
     ESADI (End Station Address Distribution Information) Protocol
                    <draft-ietf-trill-esadi-07.txt>

Abstract

   The IETF TRILL (Transparent Interconnection of Lots of Links)
   protocol provides least cost pair-wise data forwarding without
   configuration in multi-hop networks with arbitrary topologies and
   link technologies.  TRILL supports multi-pathing of both unicast and
   multicast traffic.  Devices that implement the TRILL protocol are
   called TRILL Switches or RBridges (Routing Bridges).

   ESADI (End Station Address Distribution Information) is an optional
   protocol by which a TRILL switch can communicate, in a Data Label
   (VLAN or Fine Grained Label) scoped way, end station addresses and
   other information to TRILL switches participating in ESADI for the
   relevant Data Label.  This document updates RFC 6325, specifically
   the documentation of the ESADI protocol, and is not backwards
   compatible.

Status of This Memo
