1. Introduction

 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 [BGPDPA], an
 Internet-Draft that was abandoned in 1996.  The latter are associated
 with [RFC1863], an RFC that was reclassified as Historic by [RFC4223]
 in 2005.  Neither specification is currently in use, nor have they
 ever been.

 Note that the deprecated CLUSTER_ID is distinct from CLUSTER_LIST
 [RFC4456].  CLUSTER_LIST is not being deprecated.

2. IANA Considerations

 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".

3. Security Considerations

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