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 represents 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.
