Technical Summary

   The IETF TRILL (Transparent Interconnection of Lots of Links)
   protocol includes an optional mechanism, called RBridge Channel, that
   is specified in RFC 7178, for the transmission of typed messages
   between TRILL switches in the same campus and between TRILL switches
   and end stations on the same link. This document specifies two
   optional extensions to the RBridge Channel protocol: (1) A standard
   method to tunnel a variety of payload types by encapsulating them in
   an RBridge Channel message; and (2) A method to support security
   facilities for RBridge Channel messages. This document updates RFC
   7178.

Working Group Summary

 WG Issue is part of the directory services work which 
 has received discussion over 2 years.  The WG has strong 
 consensus after this lengthy discussion on the problem
 and the set of drafts for the solution.

About implementations:

 Directory service mechanism are currently implemented as proprietary 
  fashions by every vendor that does some variant of TRILL (cisco, brocade, Huawei
  and others).  Until we get a full standard solution approved, the 
  existing vendors with "early TRILL" implementations have little reason
  to switch. 

  Huawei is planning implementations. Potentially Brocade and Cisco
  could switch to these mechanisms, but unless IETF standards are out
  as a set - this may not occur.
