Deprecation of DPA et al.

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.
