I have discovered another issue with the RAs sent out by my ER605.

This is the lifetime that I have currently configured:

The router sends RAs every two minutes, which is not often enough because when the lifetime is reached the prefix expires for a short moment causing existing connections to break.

When I change the lifetime, the interval changes as well, so it will always be a little bit too short. :(

On the Mikrotik router I was using previously I could configure the RA interval manually, but this doesn't seem to be possible with the Omada router?
