If we simply define:

``` aspa table aspas; ```

and then call a `aspa_check(aspas, ...., ...)` then I sometimes receive a ASPA_VALID back, especially for paths with only 1 ASN.

This, while that table is really empty.

The RFC wording isn’t 100% clear, but it’s exepected: https://www.ietf.org/archive/id/draft-ietf-sidrops-aspa-verification-22.html... TL;DR: if the path lenght is one, and the peer AS equals the AS path, then it’s a valid ASPA path. -- Alarig
