Could you change to use kea DHCP?
I can setup CL_OPTION_CCC on kea as below:
"option-def": [
{
"comment": "CableLabs PacketCable Primary DHCPv4 Server IP address",
"name": "CL_OPTION_CCC",
"code": 2170,
"space": "vendor-4491",
"type": "record",
"record-types": "uint16, uint16, ipv4-address",
"array": false,
"encapsulate": ""
}
"option-data": [
{
"name": "CL_OPTION_CCC",
"space": "vendor-4491",
"data": "1, 4, 0.0.0.0"
} ]
You can see the format of DHCP option as below:
The format of DHCP options is:
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

| option-code | option-len |

| option-data |
| (option-len octets) |
