Just in case you missed this blog post from Vivek."Cleaning up your RPKI invalid routes"
APNIC is obviously based in Australia and thankfully so many major operators and IXs already drop invalids. AS4608 is connected to the following upstream as what I can see from the announcements.
AS4826 VOCUS-BACKBONE-AS Vocus Connect International Backbone, AU
AS7575 AARNET-AS-AP Australian Academic and Research Network (AARNet), AU
AS1221 ASN-TELSTRA Telstra Corporation Ltd, AU
along with several IXs in AU and SG (IX-AU, EQ-IX, Edge-IX and Mega-IX) and these IXs already drop RPKI invalids (EQX-IX may be). Vocus and Telstra also drop invalids. The question is, should APNIC just rely on upstream dropping the invalids or do it themselves?
