RFC 6938 Deprecation of DPA et al. May 2013


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.
