    We would like to inform you of an experiment to evaluate alternatives
    for speeding up adoption of BGP route origin validation (research
    paper with details [A]).
    Our plan is to announce prefix with a valid
    standards-compliant unassigned BGP attribute from routers operated by
    the PEERING testbed [B, C]. The attribute will have flags 0xe0
    (optional transitive [rfc4271, S4.3]), type 0xff (reserved for
    development), and size 0x20 (256bits).
    Our collaborators recently ran an equivalent experiment with no
    complaints or known issues [A], and so we do not anticipate any
    arising. Back in 2010, an experiment using unassigned attributes by
    RIPE and Duke University caused disruption in Internet routing due to
    a bug in Cisco routers [D, CVE-2010-3035]. Since then, this and other
    similar bugs have been patched [e.g., CVE-2013-6051], and new BGP
    attributes have been assigned (BGPsec-path) and adopted (large
    communities). We have successfully tested propagation of the
    announcements on Cisco IOS-based routers running versions 12.2(33)SRA
    and 15.3(1)S, Quagga and 1.1.1, as well as BIRD 1.4.5 and
    We plan to announce from 8 PEERING locations for a
    predefined period of 15 minutes starting 14:30 GMT, from Monday to
    Thursday, between the 7th and 22nd of January, 2019 (full schedule and
    locations [E]). We will stop the experiment immediately in case any
    issues arise.
    Although we do not expect the experiment to cause disruption, we
    welcome feedback on its safety and especially on how to make it safer.
