Technical Summary
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.
