Syntax ipv6 dhcp server apply pool pool-name [ allow-hint | preference preference-value | rapid-commit ] * undo ipv6 dhcp server apply pool Default No address pool is applied to an interface. Views Interface view Predefined user roles network-admin Parameters pool-name: Specifies a DHCPv6 address pool by its name, a case-insensitive string of 1 to 63 characters. 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 Upon receiving a DHCPv6 request, the DHCPv6 server selects an IPv6 address or prefix from the address pool applied to the receiving interface. If no address pool is applied, the server selects an IPv6 address or prefix from a global address pool that matches the IPv6 address of the receiving interface or the DHCPv6 relay agent. The allow-hint keyword enables the server to assign the desired address or prefix to the client. If the desired address or prefix does not exist or is already assigned to another client, the server assigns a free address or prefix. If allow-hint is not specified, the server ignores the desired address or prefix, and assigns a free address or prefix. Only one address pool can be applied to an interface. If you use the command multiple times, the most recent configuration takes effect. 215

Usage guidelines
Upon receiving a DHCPv6 request, the DHCPv6 server selects an IPv6 address or prefix from the address
pool applied to the receiving interface. If no address pool is applied, the server selects an IPv6 address
or prefix from a global address pool that matches the IPv6 address of the receiving interface or the
DHCPv6 relay agent.
The
allow-hint
keyword enables the server to assign the desired address or prefix to the client. If the
desired address or prefix does not exist or is already assigned to another client, the server assigns a free
address or prefix. If
allow-hint
is not
specified, the server ignores the desired address or prefix, and
assigns a free address or prefix.
Only one address pool can be applied to an interface. If you use the command multiple times, the most
recent configuration takes effect.
