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.
No prefix pool is configured by default.
The prefix ranges of the prefix pools cannot overlap.
You cannot modify an existing prefix pool.
Removing a prefix pool clears all bindings of prefixes assigned from the prefix pool.

assigned as 42. Prefix pool 1 can assign 1024 prefixes in the range of 2001:0410::/42 to
2001:0410:FFC0::/42.
