Abstract:
   Although TRILL is based on IS-IS, which supports multilevel unicast
   routing, extending TRILL to multiple levels has challenges that are
   not addressed by the already-existing capabilities of IS-IS.  One
   issue is with the handling of multi-destination packet distribution
   trees. Other issues are with TRILL switch nicknames. How are such
   nicknames allocated across a multilevel TRILL network? Do nicknames
   need to be unique across an entire multilevel TRILL network or can
   they merely be unique within each multilevel area?

   This informational document enumerates and examines alternatives
   based on a number of factors including backward compatibility,
   simplicity, and scalability and makes recommendations in some cases.
