Yes, the man page is a little bit confusing. The “slaac” mode requires “—enable-ra” since it needs to manipulate MOAL bits in the RA. As matter of fact, all of the modes available for IPv6 rely on “—enable-ra”.
My understanding is, the ra-names option has nothing to do with RA. It resolves the problem of where to find DNS server. It should work with slaac mode or ra-stateless mode.
