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 represents a higher preference.
rapid-commit

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 execute this command multiple times,
the most recent configuration takes effect.
A non-existing address pool can be applied to an interface, but the server cannot assign any prefix,
address, or other configuration information from the address pool until the address pool is created.
Examples
# Apply address pool 1 to VLAN-interface 2, configure the address pool to support desired
address/prefix assignment and address/prefix rapid assignment, and set the preference to 255.
