Format

dhcpv6-server { destination destination-address [ vpn-instance vpn-name ] | interface { interface-name | interface-type interface-number } } [ weight weight-value ]

undo dhcpv6-server [ destination destination-address [ vpn-instance vpn-name ] | interface { interface-name | interface-type interface-number } ]

Parameters

Parameter	Description	Value
destination destination-address	Specifies the IP address for a destination DHCPv6 server, in the format of X:X::X:X.	The address is a 32-digit hexadecimal number.
vpn-instance vpn-name	Specifies the name of a VPN instance.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported.
interface interface-type interface-number	Specifies the outbound interface for DHCPv6 packets.	The value is an integer that ranges from 1 to 64.
weight weight-value	Specifies the load balancing weight for a DHCPv6 server.	The value is an integer that ranges from 0 to 100.

Usage Guidelines

Usage Scenario

If a remote DHCPv6 server needs to be used for address allocation, you need to configure a DHCPv6 server group and then run the dhcpv6-server command to specify a DHCPv6 server.

Prerequisites

A DHCPv6 server group to which the remote DHCPv6 server belongs must have been configured.
The algorithm for selecting DHCPv6 servers must have been set to load balancing for the DHCPv6 server group if load balancing needs to be configured.

Configuration Impact

After the dhcpv6-server destination <ipv6-address> command is run, the first address specifies the master server if DHCPv6 servers in a DHCPv6 server group work in master/backup mode.

If the parameter loading-share is specified in the dhcpv6-server algorithm { loading-share | master-backup } command, the parameter weight is valid only when you configure a DHCPv6 server.

Note that weight refers to the weight of a DHCPv6 server in load balancing rather than the priority of a DHCPv6 server. If the weight is set, packets are sent to two DHCPv6 servers according to the weight of each DHCPv6 server. If the weight is not set, packets are sent equally to two DHCPv6 servers.

Precautions

In VS mode, this command is supported only by the admin VS.

A maximum of eight DHCPv6 servers can be configured in a DHCPv6 server group.

Example

# Add two DHCPv6 servers to a DHCPv6 server group named remote.
