How can you quickly figure out if a network you are using is dropping invalid Resource Public Key Infrastructure (RPKI) BGP announcements? Simply open a web browser and visit the RIPE NCC’s RPKI test web page.
During RIPE 78, the RIPE community asked us at RIPE NCC to configure the meeting’s network in a way so invalid RPKI BGP announcements were dropped. This was indeed the current configuration, but it is not easy to check. So we built an experimental webpage where you can check if the network you are using is doing RPKI Origin Validation.
- One that is covered by a valid Route Origin Authorization (ROA)
- Another one that is invalid (on purpose of course)
There is a webserver in both that serves content, so if you cannot fetch the content from the invalid and you can do so from the valid, then it’s highly likely the network you are on is dropping invalid RPKI BGP routes.
Please test this tool and check if the network you are on drops invalid RPKI BGP announcements.
Currently, this is only available on IPv4 as we wanted to have this finished before the end of RIPE 78. We are aiming to make it available to IPv6 too, and be future-proof soon!
