General Internet Engineering Task Force BGP This document requests IANA to deprecate the following BGP path attributes: DPA, ADVERTISER, and RCID_PATH / CLUSTER_ID, associated with an abandoned Internet-Draft and a Historic RFC.

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 , an Internet-Draft that was abandoned in 1996. The latter are associated with , an RFC that was reclassified as Historic by in 2005. Neither specification is currently in use, nor have they ever been. Note that the deprecated CLUSTER_ID is distinct from CLUSTER_LIST . CLUSTER_LIST is not being deprecated.

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".

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