Restrict Router Advertisements to specific hosts?

[ShagoY]

Hello 

I have very little knowledge of IPv6/RA at the moment so it may be a silly question... Sorry in advance.

I currently have a working dual-stack IPv4/6 configuration and I am able to pass/block access to some of my IPv6 devices (DHCPv6 and RA for android).

But I wonder if it is possible to restrict the allocation of my IPv6 on one of my VLANs?

For the moment, I tried using an alias (mac address) to restrict access, it works well for in/out stream and DHCPv6 allocation but all my devices still receive an IPv6 through the RA :-(

Any advices ?
