<span class="h2"><a class="selflink" id="section-1" href="#section-1">1</a>.  Introduction</span>

   As of this writing, the BGP Path Attributes registry maintained by
   IANA contains entries for DPA, ADVERTISER, and RCID_PATH /
   CLUSTER_ID.  The first of these is associated with [<a href="#ref-BGPDPA" title=""Destination Preference Attribute for BGP"">BGPDPA</a>], an
   Internet-Draft that was abandoned in 1996.  The latter are associated
   with [<a href="./rfc1863" title=""A BGP/IDRP Route Server alternative to a full mesh routing"">RFC1863</a>], an RFC that was reclassified as Historic by [<a href="./rfc4223" title=""Reclassification of RFC 1863 to Historic"">RFC4223</a>]
   in 2005.  Neither specification is currently in use, nor have they
   ever been.

   Note that the deprecated CLUSTER_ID is distinct from CLUSTER_LIST
   [<a href="./rfc4456" title=""BGP Route Reflection: An Alternative to Full Mesh Internal BGP (IBGP)"">RFC4456</a>].  CLUSTER_LIST is not being deprecated.

<span class="h2"><a class="selflink" id="section-2" href="#section-2">2</a>.  IANA Considerations</span>

   Per this document, IANA has marked the BGP Path Attributes registry
   entries for DPA (Value 11), ADVERTISER (Value 12), and RCID_PATH /
   CLUSTER_ID (Value 13) as "deprecated".

<span class="h2"><a class="selflink" id="section-3" href="#section-3">3</a>.  Security Considerations</span>

   There are no meaningful security consequences arising from this
   registry update.
