In existing specifications, the route preferences for IPv4/IPv6
Extended Reachability TLVs are not explicitly stated.  There are also
inconsistencies in the definition of how the up/down bit applies to
route preference when the prefix advertisement appears in Level 2
Link State Protocol Data Units (LSPs).  This document addresses these
issues.

This document is a product of the IS-IS for IP Internets 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
