How to set the DHCPv6 in win2012r2 to boot ipxe.efi

[robinsmidsrod]

To get iPXE to boot via IPv6 you need a service like radvd (Router Advertisement Daemon, SLAAC I believe it is called) to advertise a router and tell the client that it is supposed to use a DHCPv6 server for more network options (like boot server and file). I'm not sure which service on Windows Server that provides this. Once you've got that operational I think you're DHCPv6 server should work as expected. I'm not sure which DHCPv6 option defines the boot file, but looking at the DHCPv6 wikipedia page or similar should probably tell you some details or point you in the right direction.
