1. Introduction
1. 介绍

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
2. IANA考虑

3. Security Considerations
3. 安全考虑

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