DHCPv6 IA_NA
Control Plane
To enable/disable DHCPv6 IA_NA client on an interface:
dhcp6 client <interface> [disable]
To show the state of clients and addresses:
show dhcp6 clients show dhcp6 addresses
Binary API:

Data Plane
Binary API:
Enable DHCPv6 client subsystem to receive UDP messages containing DHCPv6 client port: (This is to set the router to DHCPv6 client mode - so client subsystem gets the messages instead of DHCPv6 proxy subsystem)

DHCPv6 prefix delegation
Control Plane
To enable/disable DHCPv6 prefix delegation client on an interface:
dhcp6 pd client <interface> (prefix group <string> | disable)
To show the state of clients, prefixes and addresses:
show ip6 pd clients show ip6 prefixes show ip6 addresses
To add/delete IPv6 address potentially using available prefix from specified prefix group:
set ip6 address <interface> [prefix group <string>] <address> [del]
