3 CMTS and 1 DHCP server problem

Hi,

We have 3 CMTS and we want to serve fixed ip address to CM on any cmts.

cmts1 cm network: 10.100.0.0/16
cmts2 cm network: 10.101.0.0/16
cmts3 cm network: 10.102.0.0/16

We want serv to modem1:
- on cmts1 10.100.1.2
- on cmts2 10.101.1.2
- on cmts3 10.102.1.2

current dhcpd.conf:

option docsis-mta.provision-server code 3 = { integer 8, string };

option docsis-mta.tgs-util code 7 = integer 8;
option docsis-mta.timer code 8 = integer 8;
option docsis-mta.ticket-ctrl-mask code 9 = integer 16;
option docsis-mta-pkt code 122 = encapsulate docsis-mta;

option docsis-mta.dhcp-server-1 192.168.4.2;
option docsis-mta.provision-server 0 "\006docsis\007xxxxxxx\002hu\000";
option docsis-mta.krb-realm-name "\005BASIC\0011\000";

class "CM" { match hardware; vendor-option-space docsis-mta; }
class "MTA" { match hardware; }

subnet 192.168.4.0 netmask 255.255.255.0 { }

shared-network docsis {
subnet 10.100.0.0 netmask 255.255.0.0 { option routers 10.100.0.1; option subnet-mask 255.255.0.0; }
subnet 10.101.0.0 netmask 255.255.0.0 { option routers 10.101.0.1; option subnet-mask 255.255.0.0; }
subnet 10.102.0.0 netmask 255.255.0.0 { option routers 10.102.0.1; option subnet-mask 255.255.0.0; }
}

subclass "CM" 1:00:26:5A:DA:75:1F;
host cm00265ada751f { hardware ethernet 00:26:5A:DA:75:1F; filename "00265ada751f.cm"; option bootfile-name "00265ada751f.cm"; fixed-address 10.100.1.2, 10.101.1.2, 10.102.1.2; }

It's works but serve the first ip address on all cmts.
