Parameters

relay: Enables the DHCPv6 relay agent on the interface.

server: Enables the DHCPv6 server on the interface.

Usage guidelines

Before changing the DHCPv6 server mode to the DHCPv6 relay agent mode on an interface, use the following commands to remove IPv6 address/prefix bindings:

• reset ipv6 dhcp server ip-in-use

• reset ipv6 dhcp server pd-in-use

Do not configure the DHCPv6 client on the interface that has been configured as the DHCPv6 relay agent or DHCPv6 server.

Examples

# Enable the DHCPv6 server on VLAN-interface 10.

<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] ipv6 dhcp select server

# Enable the DHCPv6 relay agent on VLAN-interface 20.

<Sysname> system-view
[Sysname] interface vlan-interface 20
[Sysname-Vlan-interface20] ipv6 dhcp select relay
