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
