  6. What’s a Backbone Router? Common ND based abstraction over a backbone ScalesDADoperations (distributes 6LoWPAN NDLBR) Scales the subnetwork (high speed backbone) Allows interaction withnodes on the backbone or in othersubnets running differentoperations http://tools.ietf.org/html/draft-thubert-6lowpan-backbone-router
