ISC Dhcp and CableLabs vendor specific option 2171

[Vincent De Maertelaere]

@Patricio: Thank you for your reply.

This is what I am using in the dhcpd6.conf too,
but what I am looking for is CCCv6 for dhcpd4.conf.

I've tried a similar approach, but the DHCP daemon refused to answer to 
this particular option.
This is the layout shown by CableLabs:

OPTION_VI_VENDOR_OPTS(125)
    - CL_V4OPTION_CCCV6 (123)
       - Primary DHCPv6 server (1)
       - Secondary DHCPv6 Server (2)
       - Provisioning server address (3)
       - Kerberos REALM of the KDC (6)
    - CL_V4OPTION_IP_PREF (124)

I was trying a configuration file like this:

/etc/dhcpd4.conf
option space docsis code width 2 length width 2 hash size 100;
option docsis.tftp-servers code 32 = array of ip6-address;
option docsis.cablelabs-configuraiton-file code 33 = text;
option docsis.syslog-servers code 34 = array of ip6-address;
option docsis.time-servers code 37 = array of ip6-address;
option docsis.time-offset code 38 = signed integer 32;
option docsis.ip-pref code 39 = unsigned integer 8;

option space cccv6 code width 2 length width 2 hash size 100;
option cccv6.primary-dhcp code 1 = ip6-address;
option cccv6.prov-server code 3 = { integer 8, text };
option cccv6.krb-realm code 6 = text;

option docsis.cccv6 code 2171 = encapsulate cccv6; option vsio.docsis code
4491 = encapsulate docsis;

option cccv6.primary-dhcp <ipv6 address of the server>
...
