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
