Subject: Re: IPv6 test fail

Hello,

It seems that I’m not here for enough time, I can’t find your thread.
What were your issues on IPv6? I hit some from migrating to 4.19 (from
4.4) on routers, so I’m still on 4.4 for now.

We discussed it a bit on bird ML:
https://bird.network.cz/pipermail/bird-users/2019-June/013509.html
https://bird.network.cz/pipermail/bird-users/2019-November/013992.html
https://bird.network.cz/pipermail/bird-users/2019-December/014011.html

(sorry for the multiple links, it seems that the archive is split by
months)

By chances, are we hitting the same bug?

Regards,
Alarig Le Lay
