dhcpv6-server (DHCPv6 server group view)

Function

The dhcpv6-server command adds a DHCPv6 server or a next-hop relay agent to a DHCPv6 server group.

The undo dhcpv6-server command deletes a DHCPv6 server or a next-hop relay agent that is configured in a DHCPv6 server group.

By default, no DHCPv6 server or next-hop relay agent is configured in a DHCPv6 server group.

Format

dhcpv6-server ipv6-address [ interface interface-type interface-number ]

undo dhcpv6-server ipv6-address [ interface interface-type interface-number ]

Parameters

Parameter	Description	Value
ipv6-address	Specifies the IPv6 address of a DHCPv6 server or a next-hop relay agent.	The 128-bit IPv6 address is divided into eight groups. Each group contains four hexadecimal digits. The format is X:X:X:X:X:X:X:X.
interface interface-type interface-number	Specifies the type and number of an outbound interface for DHCPv6 packets. interface-type specifies the type of an interface. interface-number specifies the number of an interface.	-

Parameter

Specifies the IPv6 address of a DHCPv6 server or a next-hop relay agent.

The 128-bit IPv6 address is divided into eight groups. Each group contains four hexadecimal digits. The format is X:X:X:X:X:X:X:X.

interface interface-type interface-number

Specifies the type and number of an outbound interface for DHCPv6 packets.

interface-type specifies the type of an interface.
interface-number specifies the number of an interface.

Usage Guidelines

Use Scenario

The dhcpv6-server command is used on DHCPv6 relay agents. To ensure that the DHCPv6 relay agent can send DHCPv6 packets to multiple DHCPv6 servers, you can configure multiple DHCPv6 servers in a DHCPv6 server group. Multiple DHCPv6 servers can allocate IPv6 addresses and other network configuration information to DHCPv6 clients through the DHCPv6 relay agent.

A DHCPv6 client and a DHCPv6 server can have multiple DHCPv6 relay agents connected in between. A device functions as a DHCPv6 relay agent. If the device is connected to a DHCPv6 server, you need to specify the IPv6 address for the DHCPv6 server. If the device is connected to a next-hop relay agent, you need to specify the IPv6 address for the next-hop relay agent and specify the IPv6 address of the remote DHCPv6 server or the next-hop relay agent on the next-hop relay agent.

Prerequisites

A DHCPv6 server group has been created using the dhcpv6 server group command.

Precautions

If a DHCPv6 relay agent is connected to multiple DHCPv6 servers or next-hop relay agents, repeat this step. A maximum of 20 DHCPv6 servers or next-hop relay agents can be connected to the device.

Example

# Add the DHCPv6 server at fc00:1::1 to the DHCPv6 server group named dhcp-srv1.

<HUAWEI> system-view
[HUAWEI] dhcpv6 server group dhcp-srv1
[HUAWEI-dhcpv6-server-group-dhcp-srv1] dhcpv6-server fc00:1::1
