Dhcp Relay - Huawei eA660 Series User Manual

eA660 Series CPE
User Guide
Background Information
In network bridge mode, the CPE performs a layer-2 Ethernet switch function.
The CPE forwards layer-2 Ethernet data by setting up L2GRE tunnels with interconnected
network elements (NEs).
When L2 GRE tunnels are enabled, the CPE DHCP server is disabled automatically. A
computer or other telecommunication devices (such as devices connected to Wi-Fi) connected
to the CPE require static configuration when obtaining IP addresses. Alternatively, a DHCP
server can be enabled by the peer NE that has a GRE tunnel function to dynamically assign IP
addresses to the devices.
