DHCPv6 server commands address range Use address range to specify a non-temporary IPv6 address range in a DHCPv6 address pool for dynamic allocation. Use undo address range to remove the non-temporary IPv6 address range in the address pool. Syntax address range start-ipv6-address end-ipv6-address [ preferred-lifetime preferred-lifetime valid-lifetime valid-lifetime ] undo address range Default No non-temporary IPv6 address range is configured. Views DHCPv6 address pool view Predefined user roles network-admin Parameters start-ipv6-address: Specifies the start IPv6 address. end-ipv6-address: Specifies the end IPv6 address. preferred-lifetime preferred-lifetime: Specifies the preferred lifetime for the non-temporary IPv6 addresses. The value range is 60 to 4294967295 seconds, and the default is 604800 seconds (7 days). valid-lifetime valid-lifetime: Specifies the valid lifetime for the non-temporary IPv6 addresses. The value range is 60 to 4294967295 seconds, and the default is 2592000 seconds (30 days). The valid lifetime cannot be shorter than the preferred lifetime. Usage guidelines When no non-temporary IPv6 address range is specified, all unicast addresses on the subnet specified by the network command in address pool view are assignable. If a non-temporary IPv6 address range is specified, only the IPv6 addresses in the IPv6 address range are assignable. You can specify only one non-temporary IPv6 address range in an address pool. If you use the address range command multiple times, the most recent configuration takes effect. The non-temporary IPv6 address range specified by the address range command must be on the subnet specified by the network command. Examples # Configure a non-temporary IPv6 address range from 3ffe:501:ffff:100::10 through 3ffe:501:ffff:100::31 in address pool 1. system-view [Sysname] ipv6 dhcp pool 1 198
