Technical Summary

   Active-active access at the TRILL edge is the extension of flow
   level multi-pathing and rapid fail-over service available in the
   interior of a TRILL campus to end stations that are multiply
   connected to a TRILL campus edge as discussed in RFC 7379. In this
   document, a Virtual RBridge's pseudo-nickname represents the edge
   RBridge group providing active-active access to such an end
   station.


Working Group Summary

   Early discussion in the TRILL WG favored a pseudo-node nickname
   approach similar to that in this draft. Later analysis resulted in
   the three alternatives described in the Introduction to
   draft-ietf-trill-aa-multi-attach. Two of these, which can be
   deployed simultaneously in a TRILL campus, are being advanced by
   the WG, an evolved version of alternative 1 using a pseudo-nickname
   in this draft and alternative 3 in draft-ietf-trill-aa-multi-
   attach.

   There was good WG support for this draft.

Document Quality

  This document was developed by the WG over a two-year period. The
   document is of good quality and is being implemented.
