dhcpcd-discuss

Greetings! It worked.
In summary, we need to add this in dhcpcd6.conf file:

vendopt <nnnn> encap sson6
encap 242 string test

where <nnnn> is the 4-digit enterprise code.

A dhcp server (ISC), configured to respond to such request, responds as
expected.

So, all good.
Thanks, Roy, for your quick help!

Regards,
-shahid
