<font face="Calibri">Hi Tim,<br>
<br>
Currently we don't have any entries in the whitelist.<br>
The idea is to fill it with prefixes that if dropped will cause
issues to our customers. Hopefully they shouldn't remain </font><font

<p>Hello Tassos,</p>
<p><br>
</p>
<p>Very good that you started dropping invalids! This will make
the internet a safer place for everybody!</p>
<p><br>
</p>
<p>One question though: have you had any entries on your
whitelist? And if so, can you share the prefixes on it? And have
you started any actions to have the prefixes removed from the
whitelist by getting them valid somehow?</p>

<div><span class="v1tlid-translation v1translation">Hi to
everyone,<br>
<br>
I would like to inform you that it's been almost one month
since Forthnet started dropping invalid prefixes on all
peering/transit links, either national or international.
It's important to note that during this month we haven't
received any complaints.<br>
<br>
Having monitored the invalid prefixes for more than a year
and experimenting with routing them across different
links, we decided that it was time to move to the next
phase and start dropping prefixes that are declared as
invalid in the RPKI ecosystem. <br>
<br>
Two were the main </span><span class="v1tlid-translation
v1translation"><span class="v1tlid-translation
v1translation">reasons that helped us take the drop
decision: </span>a) during the last year our volume of
invalid prefixes traffic decreased from ~1% of total
traffic to less than 0,2%, b) we updated our prefix
validation policy by including a whitelist (until we
evaluate SLURM) in order to bypass issues quickly if/when
they arise.<br>
<br>
Note #1: in the context of the above actions we have
noticed that invalid prefixes </span><span
class="v1tlid-translation v1translation"><span
class="v1tlid-translation v1translation"> used for
testing purposes </span>have recently begun to grow
(each large provider creates one?). This may lead to
incorrect conclusions in the future (at least in terms of
prefixes, since i don't expect traffic from those). Maybe
these invalid prefixes should have some extra "attributes"
in order to be recognized more easily while
troubleshooting.<br>
<br>
Note #2: In order to increase adoption of a similar
policy, maybe MANRS should be updated to promote dropping
invalids. If i'm not mistaken, their current action is
about creating ROAs only.<br>
