If you specify an IPv6 prefix by
its ID, make sure the IPv6 prefix
is in effect. Otherwise, the
configuration does not take
effect.
5. (Optional.) Specify a
non-temporary IPv6 address
range.
address range
start-ipv6-address
end-ipv6-address
[
preferred-lifetime
preferred-lifetime
valid-lifetime

]
By default, no non-temporary
IPv6 address range is specified,
and all unicast addresses on the
subnet are assignable.
6. (Optional.) Specify a
temporary IPv6 address
range.
temporary address range
start-ipv6-address
end-ipv6-address
[
preferred-lifetime
preferred-lifetime

valid-lifetime ]
By default, no temporary IPv6
address range is specified, and
the DHCPv6 server cannot
assign temporary IPv6
addresses.
7. (Optional.) Create a static
binding.
static-bind address
ipv6-address/addr-prefix-length |
duid
duid [
iaid

By default, no static binding is
configured.
To add more static bindings,
repeat this step.
Configuring network parameters assignment
In addition to IPv6 prefixes and IPv6 addresses, you can configure up to eight DNS server addresses,
one domain name suffix, eight SIP server addresses, and eight SIP server domain names in an
address pool.
You can configure network parameters on a DHCPv6 server by using one of the following methods:
• Configure network parameters in a DHCPv6 address pool.
• Configure network parameters in a DHCPv6 option group, and reference the option group in a
DHCPv6 address pool.
Network parameters configured in a DHCPv6 address pool take precedence over those configured
in a DHCPv6 option group.

2. Create a DHCPv6 address
pool and enter its view.

pool-name
By default, no DHCPv6
address pools exist.
3. Specify an IPv6 subnet for
dynamic assignment.

By default, no IPv6 subnet is
specified.
The IPv6 subnets cannot be
the same in different address
pools.
If you specify an IPv6 prefix
by its ID, make sure the IPv6
prefix is in effect. Otherwise,
the configuration does not
