ISC DHCP ipv4 options and matching ipv6

Hi

I am looking to set-up ISC DHCP to support ipv6, and to migrate my existing SUN DHCP ipv4 to ISC,

finding the ipv4 options for the SUN DHCP options was ok eg
TFTPsrvN = tftp-server-name
OptBootF = bootfile-name

However if I set up a DHCPv6 does anyone know what the equivalent options are I have checked
ISC DHCPv6 Options

but can't seem to find what I am looking for anybody got any ideas

Thanks
