Configuration guidelines

You can specify only one non-temporary address range and one temporary address range in an address pool.

The address ranges specified by the address range and temporary address range commands must be on the subnet specified by the network command. Otherwise, the addresses are unassignable.

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.

An IPv6 address can be bound to only one DHCPv6 client. You cannot modify bindings that have been created. To change the binding for a DHCPv6 client, you must delete the existing binding first.

Only one subnet can be specified in an address pool. If you use the network command multiple times in a DHCPv6 address pool, the most recent configuration takes effect. If you use this command to specify only new lifetimes, the settings do not affect existing leases. The IPv6 addresses assigned after the modification will use the new lifetimes.
