Parameters
prefix-pool-number: Prefix pool number. The value ranges from 1 to 128.
preferred-lifetime preferred-lifetime: Specifies the preferred lifetime of prefixes to be assigned. The value
ranges from 60 to 4294967295, in seconds. The default value is 604800 seconds (seven days).
valid-lifetime valid-lifetime: Specifies the valid lifetime of the prefixes to be assigned. The value ranges
from 60 to 4294967295 seconds and defaults to 2592000 seconds (30 days). The valid lifetime cannot
be shorter than the preferred lifetime.
Usage guidelines
Only one prefix pool can be referenced by an address pool.
A non-existing prefix pool can be referenced by an address pool. However, no prefix is available in the
prefix pool for dynamic prefix assignment until the prefix pool is created.
You cannot modify the prefix pool referenced by an address pool, or the preferred lifetime or valid
lifetime by using the prefix-pool command. You need to remove the configuration before you can have
another prefix pool referenced by the address pool, or modify the preferred lifetime and valid lifetime.
Examples
# Apply prefix pool 1 to address pool 1, and use the default preferred lifetime and valid lifetime.

# Apply prefix pool 1 to address pool 1, and set the valid lifetime to three days, the preferred lifetime to
one day.
