1. Introduction
It has been discovered that certain BGP Path Attribute values have
been used in BGP implementations which have been deployed in the wild
while not being assigned by the IANA for such usage. This has led to
deployment problems for new technologies such as Large BGP
Communities [I-D.ietf-idr-large-community].
The squatting of values 30, 31, 129, 241, 242 and 243 has been
confirmed by the involved vendors or through source code review.
2. IANA Considerations
Per this document, IANA is requested to mark values 30, 31, 129, 241,
242, and 243 as "deprecated" in the "BGP Path Attributes" registry
under the "Border Gateway Protocol (BGP) Parameters" group. The
marking "deprecated" meaning "use is not recommended"
([I-D.leiba-cotton-iana-5226bis]).
3. Security Considerations
There are no meaningful security consequences arising from this
registry update.
