I am using ISC DHCPv6 v4.3.5 server. Cannot make the server to send the Server Unicast option. The server didn't include this option in ADVERTISE or REPLY.

I used 
"option dhcp6.unicast 2000::101;"
Based on ISC DHCPV6 options http://www.ipamworldwide.com/ipam/isc-dhcpv6-options.html: 

12	OPTION_UNICAST	dhcp6.unicast	IPv6 address

that should work. 

What do I need to configure on the server, to see the unicast option in ADVERTISE?
