Status of This Memo

This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet- Drafts is at http:/⁠/⁠⁠drafts/⁠current/⁠.

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 [draft-ietf-idr-bgp-dpa-05], 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 of these specifications is in use now, nor ever was.

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

2. IANA Considerations

This document requests IANA to mark 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.
