DHCPv6 Server - Vendor Specific Options not included in the REALY-REPLY

[Adrian Cappelletti]

Hi all,

I have just installed the ISC DHCP server 4.0.2rc1 in my Ubuntu Box.
I want ot use it for IPv6. The requests come from a RELAY-AGENT that is a CMTS (for DOCSIS 3.0).

I hae dfined some Vendor specific options according to the CaleLabs specs. Details can be seen below.
The problem I have is the FWR-RELAY arrives from the CMTS and the the answer goes back "without" any of the specific options requested by the Cable modem that is trying to register.

What do i need to do to get the DHCP server to include those Vendor Specific options in the response ?

here is the config file I'm using:

cable at as-cable-rack-server-desktop:~$ sudo cat /etc/dhcp/dhcpd.conf 
#
# Define the DOCSIS option space.
#
option space docsis code width 2 length width 2 hash size 17;
option docsis.tftp-servers code 32 = array of ip6-address;
option docsis.cablelabs-configuration-file code 33 = text;
option docsis.cablelabs-syslog-servers code 34 = array of ip6-address;
option docsis.device-id code 36 = string;
option docsis.time-servers code 37 = array of ip6-address;
option docsis.time-offset code 38 = signed integer 32;
option vsio.docsis code 4491 = encapsulate docsis;

option docsis.tftp-servers 2001:DB8:12FF:100:212:79FF:FE3A:48FA;
option docsis.cablelabs-configuration-file "DPC3000-135c.bin";
option docsis.cablelabs-syslog-servers 2001:DB8:12FF:100:212:79FF:FE3A:48FA;
option docsis.time-servers 2001:DB8:12FF:100:212:79FF:FE3A:48FA;
option docsis.time-offset 0;


default-lease-time 600;
max-lease-time 7200; 
log-facility local7; 

subnet6  2001:DB8:12FF:100::/64 {
        # Range for clients
        #range6  2001:DB8:12FF:61::10  2001:DB8:12FF:61::100;
        # Additional options
}


subnet6  2001:DB8:12FF:61::/64 {
        # Range for Cable Modems
        range6  2001:DB8:12FF:61::10  2001:DB8:12FF:61::100;
 
}


Thanks in advance!
Adrian
