<abstract>
<t>This document describes a new optional type of OSPF area, somewhat humorously referred to as a "not-so-stubby" area (or NSSA).  NSSAs are similar to the existing OSPF stub area configuration option but have the additional capability of importing AS external routes in a limited fashion.</t></abstract></front>
