This document defines a bit called the Host-bit (H-bit).  This bit enables a router to advertise that it is a non-transit router.  This document also describes the changes needed to support the H-bit in the domain.  In addition, this document updates RFC 6987 to advertise Type 2 External and Not-So-Stubby Area (NSSA) Link State Advertisements (LSAs) (RFC 3101) with a high cost in order to repel traffic effectively.",
