 Yes, at the latest.  I originally planned it before 12.0 but not
 happened for some non-technical reasons.

 In this configuration dhcp6c does not work because lo1 has no L2
 address to generate an interface ID which will be used with the /64
 prefix.  Is there any specific reason why you want to use a loopback
 interface?
