LDAP/DHCP config

Hello,

I have a problem with ldap/dhcp provisioning server. The cable modem and MTA takes IP normally but the CPE router(WAN) does not.
I dont know where the problem is. Below is the config that the dhcp takes from LDAP:

authoritative;
deny duplicates;
one-lease-per-client on;
update-conflict-detection on;
allow leasequery;
option space vsi;
option vsi.version code 6 = string;
option vsi.model code 9 = string;
option vsi.vendor code 10 = string;
option vsi-pkt code 43 = encapsulate vsi;
option space docsis-mta;
option docsis-mta.dhcp-server-1 code 1 = ip-address;
option docsis-mta.dhcp-server-2 code 2 = ip-address;
option docsis-mta.web-server code 72 = ip-address;
option docsis-mta.provision-server code 3 = { integer 8, ip-address };
option docsis-mta.as-req-as-rep-1 code 4 = { integer 32, integer 32, integer 32 };
option docsis-mta.as-req-as-rep-2 code 5 = { integer 32, integer 32, integer 32 };
option docsis-mta.krb-realm-name code 6 = string;
