ipv6 dhcp server

Use ipv6 dhcp server to configure global address assignment on an interface. The server on the interface uses a global address pool to assign configuration information to a client.

Use undo ipv6 dhcp server to restore the default.

Syntax

ipv6 dhcp server { allow-hint | preference preference-value | rapid-commit } *

undo ipv6 dhcp server

Default

The server does not support desired address/prefix assignment or rapid address/prefix assignment. The server preference is set to 0.

Views

Interface view

Predefined user roles

network-admin

Parameters

allow-hint: Enables desired address/prefix assignment.

preference preference-value: Specifies the server preference in Advertise messages, in the range of 0 to 255. The default value is 0. A greater value specifies a higher preference.

rapid-commit: Enables rapid address/prefix assignment involving two messages.

Usage guidelines

The allow-hint keyword enables the server to assign the desired address or prefix to the requesting client. If the desired address or prefix is not included in any global address pool, or is already assigned to another client, the server assigns the client a free address or a prefix. If the allow-hint keyword is not specified, the server ignores the desired address or prefix, and selects an address or prefix from a global address pool.

If you use the ipv6 dhcp server and ipv6 dhcp server apply pool commands on the same interface, the ipv6 dhcp server apply pool command takes effect.

Examples

# Configure global address assignment on the interface VLAN-interface 2. Use the desired address/prefix assignment and rapid address/prefix assignment, and set the server preference to the highest 255.

<Sysname> system-view
