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 and 129 has been confirmed by the involved vendors.

2. IANA Considerations

Per this document, IANA has marked values 30, 31 and 129 as "deprecated" in the "BGP Path Attributes" registry under the "Border Gateway Protocol (BGP) Parameters" group.

3. Security Considerations

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

4. Informative References

Appendix A. Acknowledgements

The author would like to gratefully acknowledge Marlien Vijfhuizen who helped discover the squatting of value 30.
