Description
Use ipv6 dhcp prefix-pool to create a prefix pool and specify the prefix and the length of the prefix assigned.
Use undo ipv6 dhcp prefix-pool to remove the prefix pool.

The prefix ranges of the prefix pools cannot overlap.
You cannot modify an existing prefix pool.
Removing a prefix pool clears all PDs assigned from the prefix pool.
