Parameters
prefix/prefix-length: Specifies the IPv6 subnet for dynamic allocation. The value range for prefix-length is 1 to 128.
preferred-lifetime preferred-lifetime: Specifies the preferred lifetime. The value range is 60 to 4294967295 seconds, and the default is 604800 seconds (7 days).
valid-lifetime valid-lifetime: Specifies the valid lifetime. The value range is 60 to 4294967295 seconds, and the default is 2592000 seconds (30 days). The valid lifetime must be longer than or equal to the preferred lifetime.
Usage guidelines
You can specify only one subnet for a DHCPv6 address pool. If you use the network command multiple times, the most recent configuration takes effect.
Modifying or removing the network configuration removes assigned addresses in the current address pool.
Examples
# Specify the subnet 3ffe:501:ffff:100::/64 in DHCPv6 address pool 1.
<Sysname> system-view [Sysname] ipv6 dhcp pool 1 [Sysname-dhcp6-pool-1] network 3ffe:501:ffff:100::/64
