prefix prefix/prefix-len: Specifies the prefix and prefix length. The value range for the prefix length is
1 to 128.
duid duid: Specifies a client DUID. The value is an even hexadecimal number in the range of 2 to
256.
iaid iaid: Specifies a client IAID. The value is a hexadecimal number in the range of 0 to FFFFFFFF.
If you do not specify an IAID, the server does not match the client IAID for prefix assignment.
preferred-lifetime preferred-lifetime: Specifies the preferred lifetime of the address or prefix. The
value range is 60 to 4294967295 seconds, and the default is 604800 seconds (7 days).
valid-lifetime valid-lifetime: Specifies the valid lifetime of the address or prefix. 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
You can specify multiple static bindings in a DHCPv6 address pool.
An IPv6 address or prefix 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.
Examples
# In address pool 1, bind IPv6 address 2001:0410::/35 to the client DUID 0003000100e0fc005552
and IAID A1A1A1A1.

# In address pool 1, bind prefix 2001:0410::/35 to the client DUID 00030001CA0006A400 and IAID
