Configuring the DHCPv6 Relay Function

This section provides a sample of configuring the DHCPv6 relay function using the rpc method.

**Table 1** Configuring the DHCPv6 relay function
Operation	XPATH
rpc	/huawei-dhcp:dhcp-config/dhcpv4-config/enable /huawei-dhcp:dhcp-config/dhcpv6-config/dhcp-relay-configuration

Data Requirements

Item	Data
Whether DHCP is enabled	true
Name of the interface where DHCPv6 relay is enabled	VLANIF4000
IPv6 address of the proxy DHCPv6 server	fe80:2::1
Name of the source interface	Loopback2

Request Example

Ensure that VLANIF4000 and its IPv6 address have been configured and the IPv6 address of LoopBack2 has been configured before configuring this example.
