Configuring IPv6 address assignment Use one of the following methods to configure IPv6 address assignment: • Configure a static IPv6 address binding in an address pool: If you bind a DUID and an IAID to an IPv6 address, the DUID and IAID in a request must match those in the binding before the DHCPv6 server can assign the IPv6 address to the requesting client. If you only bind a DUID to an IPv6 address, the DUID in a request must match the DUID in the binding before the DHCPv6 server can assign the IPv6 address to the requesting client. • Specify a subnet and address ranges in an address pool: { Non-temporary address assignment-The server selects addresses from the non-temporary address range specified by the address range command. If no non-temporary address range is specified, the server selects addresses on the subnet specified by the network command. { Temporary address assignment-The server selects addresses from the temporary address range specified by the temporary address range command. If no temporary address range is specified in the address pool, the DHCPv6 server cannot assign temporary addresses to clients. 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 new configuration overwrites the old one. If the new configuration has the same subnet as but different preferred lifetime and valid lifetime from the previous configuration, the new preferred lifetime and valid lifetime are effective only to the IPv6 addresses not assigned to DHCPv6 clients.
