Technical Summary

   The Open Shortest Path First Version 2 (OSPFv2) does not have a
   mechanism for a node to repel transit traffic if it is on the
   shortest path.  This document defines a bit (Host-bit) that enables a
   router to advertise that it is a non-transit router."  It 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 NSSA LSAs with a high cost in order to repel traffic effectively.
