The Open Shortest Path First Version 2 (OSPFv2) protocol does not
have a mechanism for a node to repel transit traffic if it is on the
shortest path.  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.

This document is a product of the Link State Routing Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
