How to include vendor-specific option 17 suboptions 11, 12 and 13 in DHCPv6 solicit/request using dhclient

My request is to include option 17 sub-options 11, 12 and 13 in DHCPv6 solicit/request and I configured the same in dhclient6.conf on my Ubuntu as below.

Quote:

send dhcp6.vendor-opts send dhcp6.vendor-opts 00:00:0d:e9:00:0b:00:06:42:44:56:45:52:30:00:0c:00:03:6c:61:6e:00:0c:00:06:76:61:61:75:61:39;

From packet trace I can see option 17 in solicit/request but sub-options are not proper and I guess not encapsulated.
Output snippet from tshark:
