How to configure IPv6 RA?

Software SW help
1

I would like to change the RA sent by the Omnia (add resolvers, change some parameters) but I do not find where it is configured or even which daemon is used. OpenWRT used radvd but it seems deprecated https://wiki.openwrt.org/doc/uci/radvd The doc mentions odhcpd but it does not seem to run on my Omnia.

Nevertheless, the routers does send RA, with its default parameters.

Any idea how to change them?

Openwrt/TurrisOS uses odhcpd for RA/DHCPv6

Some Documentation can be found here:

Windows 7 (I dont know about 10) needs a dhcpv6 Server to recognize dns servers. Apple iOS Devices use the rdns entry that is distributed via Router advertisements. I have Win7 clients and try to avoid using dhcpv6 for Address assignment, as windows keeps the addresses even if you connect to another Wlan etc. until the lease expires. What i did with my turris is to configure odhcpd to assign DNS Server via dhcpv6, but leave the address assignment to RA autoconfiguration. I. e. setting the O Flag but not the M Flag in RA. For more information see: Controller Based WLANs - Airheads Community

my configuration looks like this:
/etc/config/dhcp:

config dhcp 'lan'
        option interface 'lan'
        option start '100'
        option limit '150'
        option leasetime '12h'
        option dhcpv6 'server'
        option ra 'server'
        option ra_management 0
        list dns 2a02:168:8605:2::1
        list dhcp_option '6,10.2.1.1'
        list domain 'fmf.netz'

/etc/config/network

config interface 'lan'
            option ifname 'eth0 eth2'
            option force_link '1'
            option type 'bridge'
            option proto 'static'
            option ipaddr '10.2.1.1'
            option netmask '255.255.255.0'
            option ip6assign '64'
            option ip6hint '2'

This gives me this IPs in Win7 and works for iOS, too
