@Slawek Kaplonski,

Yes, there are two cases here:

* Create a fresh HA router doesn't work
* Migrate a router to HA doesn't work

This bug report is about the latter and I can reproduce it. When I did further trouble shooting, I found that creating a fresh HA router didn't work either. I tracked down both issues and it looks the root cause is the same (it is because the backup router sent RA packet which interrupts the switch's learning). Disabling RA on backup router and enable ipv6 forwarding as this bug mentioned resolved the issue.

Therefore, I think it is the same bug.
