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.

R1(config-if)#<input>ipv6 dhcp relay destination FE80::250:A2FF:FEBF:A056 fastethernet0/1</input>

To global unicast
