I’ve went back and forth on solutions for RTBH, and my latest opinion is
vendors should implement a separate knob to bypass maxLength checking for
specifically routes tagged as BLACKHOLE, and still validate origin AS via
RPKI-ROV. The risk of operators using such a knob in “a bad way” is known,
but we need this tool. Let’s talk about this more at NANOG 98.


Yes. And this is possible today on Junos, as Martin Tonusoo shared in
this list (not this thread) earlier.
