Abstract

   This document moves RFC3627 (Use "Use of /127 Prefix Length Between Routers
   Considered Harmful) Harmful" (RFC 3627) to HISTORIC Historic status to reflect the
   updated guidance contained in RFC6164 (Using "Using 127-Bit IPv6 Prefixes on Inter-
   Router Links).  While a standards track Links" (RFC 6164).  A Standards Track document already supersedes an
   informational document and therefore RFC6164 document; therefore, RFC 6164 is the appropriate
   guidance to follow be followed when
   the two documents are in conflict, this conflict.  This document links the two documents RFCs
   so that it is clearer that the IETF has IETF's updated guidance on the matter. this topic is clearer.

   This document moves "Use of /127 Prefix Length Between Routers
   Considered Harmful" RFC 3627 [RFC3627] to HISTORIC Historic status in
   accordance with RFC 2026 [RFC2026].  It  RFC 3627 has been superseded by
   "Using 127-Bit IPv6 Prefixes on Inter-Router Links" RFC 6164
   [RFC6164].  While a standards track  A Standards Track document already supersedes an informational document and therefore RFC6164
   document; therefore, RFC 6164 is the
   appropriate guidance to follow be followed when the two
   documents are in
   conflict, this conflict.  This may not be have been clear to casual
   readers who are not
   completely familiar with the differences in IETF document
   types.  This document adds the necessary link between the two documents RFCs so
   that those users referring to RFC3627 RFC 3627 for guidance will see that it has
   been obsoleted by updated guidance on the matter, thus hopefully
   eliminating any confusion that may be present.
