Re: [Sidrops] Talk: RPKI Deployment: Status, Challenges and the Learning-Validator

I was about to ask a question on the mic but was late to the line. Maybe 
it’s worth sharing it here:

- How we define a ROA to be “wrong” ? One that invalidates routes or 
one that causes legitimate traffic to be dropped ?

Why? because we’ve seen in many cases ROAs that create lots of 
invalids but validate a less-specific route that covers those invalids

In a way, this even a positive side-effect, sort of vacuum-cleaning your 
routing tables.

I believe analyzing what ROAs are wrong is quite important, but i’d 
believe this particular case should not count as wrong.

thanks!
