Step 4 Create a DHCP Option 60 domain.
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
Step 5 Set the IP address of the gateway for the DHCP domain.
huawei(config)#interface vlanif 100
huawei(config-if-vlanif100)#dhcp domain docsis gateway 10.10.224.1 //Set the IP
address of the gateway for the CM domain to 10.10.224.1.
huawei(config-if-vlanif100)#quit

15.3.2.4 Configuring a Route
This section describes how to implement network communication by configuring a route in
Layer 3 networking with an optical line terminal (OLT). Through the route, packets are
forwarded at Layer 3 between the OLT and its upper-layer devices or servers.
Prerequisites
The upper-layer router of an OLT has been configured.
