Match dhcp6.remote-id to CLASS

[Jose Jr. Catubigan]

Hi All,

Manage to match the remote-id using Vendor Specific Information Option.

see below the working config.

---------------------------------------------------------------------------------------------------------

authoritative;

log-facility local6;


# Declare the option space.

  option space docsis code width 2 length width 2 hash size 100;


# Define DOCSIS option formats.

  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.cm-mac-address code 1026 = string;


# Anchor the docsis option space under the VSIO option.

  option vsio.docsis code 4491 = encapsulate docsis;


log (info, concat("Cable Modem Mac: ", v6relay(1, (binary-to-ascii(16, 8,
":", option docsis.cm-mac-address)))));

log (info, concat("Normal Lease: ",
binary-to-ascii(16,16,":",substring(option dhcp6.ia-na, 16, 16))));


# IPv6 CPE Class

class "CPE.v6" {match v6relay(1, option docsis.cm-mac-address);}


subclass "CPE.v6" 08:80:39:AC:C9:C0;


shared-network lab-cpe {

        subnet6 2001:d800:4010::/48 {

                deny unknown-clients;

                option dhcp6.name-servers 2001:d800:1000:1::2;

                default-lease-time 3600;

                max-lease-time 3600;

                        # CPE.v6

                        pool6 {

                                range6 2001:d800:4010::2 2001:d800:4010::10;

                                allow members of "CPE.v6";

                        }


                        # Fallback pool

                        pool6 {

                                range6 2001:d800:4010::11
2404:3c00:4010::20;

                        }

}

}
