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 to support desired
address/prefix assignment and rapid address/prefix assignment and set the server preference to the
highest 255.
