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.
To modify the prefix pool in a DHCPv6 address pool, execute the undo prefix-pool command to
remove the prefix pool, and then execute the
prefix-pool
command.
