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

If you do not specify a non-temporary IPv6 address range, all unicast addresses on the subnet specified by the network command in address pool view are assignable. If you specify a non-temporary IPv6 address range, only the IPv6 addresses in the specified IPv6 address range are assignable.

You can specify only one non-temporary IPv6 address range in an address pool. If you execute this 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.

<Sysname> system-view
[Sysname] ipv6 dhcp pool 1
[Sysname-dhcp6-pool-1] network 3ffe:501:ffff:100::/64
[Sysname-dhcp6-pool-1] address range 3ffe:501:ffff:100::10 3ffe:501:ffff:100::31
