Technical Summary

  This document describes mechanisms for providing directory service to
   TRILL (Transparent Interconnection of Lots of Links) edge switches.
   The directory information provided can be used in reducing multi-
   destination traffic, particularly ARP/ND and unknown unicast
   flooding. It can also be used to detect traffic with forged source
   addresses.  Directory Service can utilize either a push or a pull mechanism. 

Working Group Summary

This document is the result of 3 years of intensive discussion. 
The WG consensus was complete even if the WG discussion at the
end of the three years was "Time to send this to IESG".
