Advertise Name Server address for IPv6 Lan from Ubuntu router

[ritazreiby]

Hello,

we are trying to set up an Ipv6 LAN with the following address range 2a00:1580:8000:6::/64

the IPv6 hosts are directly connected to a switch , which is connected to the router through the interface eth1 that has the address: 2a00:1580:8000:6::5/64

we installed and configured Radvd like this :

interface eth1 { 

    AdvSendAdvert on;
    MinRtrAdvInterval 3; 
        MaxRtrAdvInterval 10;
    AdvManagedFlag off;
    AdvOtherConfigFlag off;
    RDNSS 2a00:1580:8000:6::5
    {
    AdvRDNSSPreference 255;    
    
        };    
    prefix 2a00:1580:8000:6::/64 { 
                AdvOnLink on; 
                AdvAutonomous on; 
                AdvRouterAddr on;
        
        };
    
};

but it seems like our hosts can't obtain the dns name server adress automatically.
(the dns name server is the adress of eth1)

we tried to configure wide-dhcpv6 but didnt work.

please if you can provide us with step by step tutorial

Thanks
