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.

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".

Security Considerations

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