Usage Guidelines

Usage Scenario

The ip relay address command is applicable to DHCP relay agents. When a DHCP client needs to send a DHCP request packet to a DHCP server on a different network segment by using a DHCP relay agent, run the ip relay address command on the DHCP relay agent to configure a DHCP server address.

Prerequisites

DHCP relay has been enabled on the VLANIF interface by using the dhcp select relay command.

Precautions

If you run the ip relay address command multiple times, multiple DHCP server addresses are configured.

Example

# Configure DHCP server addresses 10.2.2.2 on VLANIF100 enabled with DHCP relay.

[HUAWEI] dhcp enable
[HUAWEI] interface vlanif 100
[HUAWEI-Vlanif100] dhcp select relay
