A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Transparent Interconnection of Lots of Links of the IETF. Title : Alternatives for Multilevel TRILL (Transparent Interconnection of Lots of Links) Authors : Radia Perlman Donald Eastlake Mingui Zhang Anoop Ghanwani Hongjun Zhai Filename : draft-ietf-trill-rbridge-multilevel-06.txt Pages : 33 Date : 2017-06-16 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.
