A. DSW1 (config-if)# ipv6 helper address 2002:404:404::404:404
B. DSW1 (config)#ipv6 route 2002:404:404::404:404/128 FastEthernet 1/0
C. DSW1 (dhcp-config)# default-router 2002:A04:A01::A04:A01
D. DSW1 (config-if)# ipv6 dhcp relay destination 2002:404:404::404:404 GigabitEthernet 1/2

Correct Answer: D

Explanation:
Specifies a destination address to which client packets are forwarded and enables DHCPv6 relay service on the interface.

ipv6 dhcp relay destination ipv6-address[interface-type interface-number]

Example:
Router(config-if) ipv6 dhcp relay destination FE80::250:A2FF:FEBF:A056 ethernet 4/3
