Automatic DNS configuration on IPv6

[zirbo]

Guys,

I am stuck on a simple task: provide DNS information to a host sitting behind an IPv6 gateway (C881W)

I have tried both DHCPv6 and NDP - without result.

(the host - Win10 - somehow gets an IPv6 address that is in line with the gateway LAN interface address but no DNS info.

It all works perfectly if I manually set the DNS on host.

Can anybody provide a sample script I can take as a reference to try differently from what I already did ?

Thanks in advance.

Kind Regards,

Dragos

Hi,

What are you using for your  DHCPv6 server?

Thanks

Hi, John

I am using the DHCP service on the C881W router.

ipv6 dhcp pool v6
address prefix X:X:X:X::/64
dns-server 2001:4860:4860::8888

interface Vlan1
no ip address
ip virtual-reassembly in
ipv6 address X:X:X:X::1/64
ipv6 nd other-config-flag
ipv6 nd ra dns server 2001:4860:4860::8888
ipv6 dhcp server v6

Thanks,
