Hello,
Following the 2.16 release with ASPA support, I tried to play with it. So I tried to connect a bird instance to a RTR server with version 2 as stated by https://bird.network.cz/?get_doc&v=20&f=bird-6.html#ss6.16
The same protocol, since version 2, also receives and maintains a set of ASPAs. You can then validate AS paths using function aspa_check() in (import) filters.
It seems that I misconfigured my routinator, but instead of an error with a timer, it tries to reconnect right away, which fail again, etc.
Hello So if i undestand it correctly, if you put both 'min version 2' and 'max version 2', it failed? (that is expected if the peer does not support version 2) If you remove that option or put lower number it worked? I see here two issues: 1) There should be some timeout between retries. 2) The RPKI protocol outline in documentation should not contain 'min version 2' but 'min version <num>' as it is just an outline of options, not an example. Is that what you mean? Also it is funny that Routinator answered with: 'only versions 0 up to and including MAX_VERSION supported' without stating what is the MAX_VERSION.

And here is the config I used: protocol rpki rpki_rr3 { debug all; roa4 { table r4; }; roa6 { table r6; }; aspa { table at; };
remote "rr3.swordarmor.fr"; min version 2; max version 2; disabled; }
