docsis     //Set the IP address of the DHCP domain gateway for CMs.

pktc     //Set the IP address of the DHCP domain gateway for MTAs.

huawei(config-if-vlanif100)#ip address 10.100.8.1 255.255.255.0 sub description

huawei(config-if-vlanif100)#quit
Step 2 Configure the working mode of the DHCP relay to Layer 3 Option 60.
In DHCP Option 60 mode, a DHCP server group is selected according to the Option 60 domain
name in DHCP packets. Users in this mode are identified by domain information of packets,
which differentiates various service types in a VLAN. Ensure that the Option 60 domain name
and the DHCP server group bound to the Option 60 domain name are configured beforehand.
huawei(config)#dhcp mode layer-3 Option60
  Several minutes may be required and no action can be taken during this period 
  Are you sure to perform this operation? (y/n)[n]: y
Step 3 Enable the DHCP option82 feature.
The DHCP feature does not have any mechanism for authentication or security. Thus, the DHCP
feature encounters many security problems when it is used in the network. To solve these
problems, the DHCP option82 is introduced.
huawei(config)#dhcp option82 enable
Step 4 Set the IP addresses of the servers in a DHCP server group.
huawei(config)#dhcp-server 0 ip 192.168.10.10 192.168.10.11    //Configure DHCP 
server group 0 to assign IP addresses to CMs and MTAs.
huawei(config)#dhcp-server 1 ip 192.168.10.12 192.168.10.13    //Configure DHCP 
server group 1 to assign IP addresses to PCs and STBs.
Step 5 Create a DHCP Option 60 domain.
huawei(config)#dhcp domain default   //Create Option 60 domain name default for 
PCs.
huawei(config-dhcp-domain-default)#dhcp-gateway learning enable   //Paid and 
overdue PCs are in different network segments. Therefore, self-learning needs to be 
enabled on OLT gateways.
huawei(config-dhcp-domain-default)#dhcp-server 1 vlan 100    //Bind DHCP server 
group 1 to the DHCP domain where the PCs locate. After the configuration, the PCs 
in the DHCP domain are corresponded to DHCP server group 1.
huawei(config-dhcp-domain-default)#quit
huawei(config)#dhcp domain docsis   //Create Option 60 domain name docsis for CMs.
huawei(config-dhcp-domain-docsis)#dhcp-server 0 vlan 100       //Bind DHCP server 
group 0 to the DHCP domain where the CMs locate. After the configuration, the CMs 
in the DHCP domain are corresponded to DHCP server group 0.
huawei(config-dhcp-domain-docsis)#quit
huawei(config)#dhcp domain pktc   //Create Option 60 domain name pktc for MTAs.
huawei(config-dhcp-domain-pktc)#dhcp-server 0 vlan 100       //Bind DHCP server 
group 0 to the DHCP domain where the MTAs locate. After the configuration, the CMs 
in the DHCP domain are corresponded to DHCP server group 0.
huawei(config-dhcp-domain-pktc)#quit
huawei(config)#dhcp domain stb   //Create Option 60 domain name stb for STBs.
huawei(config-dhcp-domain-stb)#dhcp-server 1 vlan 100      //Bind DHCP server group 
1 to the DHCP domain where the STBs locate. After the configuration, the STBs in 
the DHCP domain are corresponded to DHCP server group 1.
huawei(config-dhcp-domain-stb)#quit
Step 6 Set IP addresses of the gateways for the DHCP domain.
huawei(config)#interface vlanif 100
huawei(config-if-vlanif100)#dhcp domain default gateway 10.100.187.1
