how does a client(PC) get a DNS address?

[callmebefore]

how does a client(PC) get a DNS address while it uses auto-configuration based on using the EUI-64? i have tried to configure as follows, it works good getting the ipv6 address (prefix and prefix length), default router but it is missed the very important piece the DNS ipv6 address. so I always depend on you guys that you are as my family to call to make things right for me regarding the Network issue that clicks in mind and thanks for your time and knowledge.

Router(config)# int g0/1

Router(config-if)#

Router(config-if)#ipv6 address 2001:abc0:10:20::1/64 eui-64

Router(config-if)#ipv6 enable

Router(config-if)#exit

Router(config)#ipv6 unicast-routing

Router(config)#

I am look for the configuration how a PC gets DNS IPv6 address based on the EUI-64.

Hello,

if I remember it correctly, for EUI-64 you typically use Router Advertisement (RA) options:

ipv6 nd other-config-flag
ipv6 nd ra dns-server <DNS_Server_IPv6_Address1> <DNS_Server_IPv6_Address2>

ipv6 address autoconfig

thanks for your solution and here the correct configuration

Router>Enable

Router#Config t

Router(config)#

Router(config-if)#int g0/1

Router(config-if)#ipv6 address 2001:abc0:10:20::1/64 eui-64

Router(config-if)#no sh

Router(config-if)#ipv6 enable

Router(config-if)#exi




Router(config)#ipv6 unicast-routing

Router(config)#ipv6 nd other-config-flag
Router(config)#ipv6 dhcp pool our_pool

Router(config-dhcpv6)#dns-server 2001:abc1:1234:30::1

Router(config-dhcpv6)#int g0/0

Router(config-if)#ipv6  dhcp server our_pool

Router(config-if)# do sh run
