This article will be written when the author gets experience using DHCPv6. (Hopefully shortly :-)
DHCPv6 multicast
- Local link DHCPv6 multicast FF02::1:2
- Entire site DHCPv6 multicast FF05::1:3
- NOTE
- When using multicast remember to enable ipv6 multicast routing
ipv6 multicast-routing
DHCPv6 other-config-flag
Node will autoconfigure its IPv6 address using |Stateless Autoconfiguration. The ipv6 nd other-config-flag teels the node to collect remaining setup from DHCPv6- in this case DNS-server IP.

On local link
R1(config)#<input>interface fastethernet 0/0</input>
R1(config-if)#<input>ipv6 dhcp relay destination FE80::250:A2FF:FEBF:A056 fastethernet0/1</input>
To global unicast
R1(config)#<input>interface fastethernet 0/0</input>
R1(config-if)#<input>ipv6 dhcp relay destination 2001:16D8:DD85:146::2</input>
R1(config-if)#<input>ipv6 dhcp relay source-interface loopback 0</input>
To Multicast All Site Local DHCPv6 servers
R1(config)#<input>interface fastethernet 0/0</input>
R1(config-if)#<input>ipv6 dhcp relay destination FF05::1:3</input>
Troubleshooting
