    abstract =  {This document describes an extension to the Open Shortest Path First (OSPF) protocol to allow a single physical link to be shared by multiple areas. This is necessary to allow the link to be considered an intra-area link in multiple areas. This would create an intra- area path in each of the corresponding areas sharing the same link. {[}STANDARDS-TRACK{]}},
