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

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 and domain-name.
