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.

Extracted elements (5)

design-rationale §1

ADVERTISER (Value 12) and RCID_PATH / CLUSTER_ID (Value 13) are deprecated because they are defined in RFC 1863, which was reclassified as Historic by RFC 4223 in 2005, and neither attribute has ever been in use.

bgp

design-rationale §1

DPA (Value 11) is deprecated because its defining specification, an Internet-Draft by Chen and Bates titled 'Destination Preference Attribute for BGP', was abandoned in 1996 and was never deployed.

bgp

interoperability-note §1

The deprecated CLUSTER_ID (Value 13, from RFC 1863) is distinct from CLUSTER_LIST defined in RFC 4456 for BGP Route Reflection. CLUSTER_LIST is not being deprecated and remains in active use.

bgp

registry §2

IANA has marked BGP Path Attributes registry entries for DPA (Value 11), ADVERTISER (Value 12), and RCID_PATH / CLUSTER_ID (Value 13) as 'deprecated'. These entries previously existed without active specifications.
