Parameters
prefix-pool-number: Specifies a prefix pool by its number in the range of 1 to 128.
preferred-lifetime preferred-lifetime: Specifies the preferred lifetime in the range of 60 to
4294967295 seconds. The default value is 604800 seconds (7 days).
valid-lifetime valid-lifetime: Specifies the valid lifetime in the range of 60 to 4294967295 seconds.
The default value is 2592000 seconds (30 days). The valid lifetime must be longer than or equal to
the preferred lifetime.
Usage guidelines
Only one prefix pool can be applied to an address pool.
You can apply a prefix pool that has not been created to an address pool. The setting takes effect
after the prefix pool is created.
You cannot modify prefix pools that have been applied. To change the prefix pool for an address
pool, you must remove the prefix pool application first.
Examples
# Apply prefix pool 1 to address pool 1, and use the default preferred lifetime and valid lifetime.
<Sysname> system-view
[Sysname] ipv6 dhcp pool 1
[Sysname-dhcp6-pool-1] prefix-pool 1
# Apply prefix pool 2 to address pool 2, and set the preferred lifetime to one day and the valid lifetime
to three days.
<Sysname> system-view
[Sysname] ipv6 dhcp pool 2
[Sysname-dhcp6-pool-2] prefix-pool 2 preferred-lifetime 86400 valid-lifetime 259200
