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.
