Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
(Optional.) Specify the IPv6
addresses excluded from
dynamic assignment.
ipv6 dhcp server
forbidden-address
start-ipv6-address
[
end-ipv6-address
]
[
vpn-instance
vpn-instance-name
]
By default, all IPv6 addresses
except for the DHCPv6 server's
IP address in a DHCPv6 address
pool are assignable.
If the excluded IPv6 address is in
a static binding, the address still
can be assigned to the client.
To exclude multiple IPv6 prefix
ranges, repeat this step.
3.
Create a DHCPv6 address
pool and enter its view.
ipv6 dhcp pool
pool-name
By default, no DHCPv6 address
pools exist.
4.
Specify an IPv6 subnet for
dynamic assignment.
network
{
prefix/prefix-length
|
prefix
prefix-number
[
sub-prefix/sub-prefix-length
] }
[
preferred-lifetime
preferred-lifetime
valid-lifetime
valid-lifetime
]
By default, no IPv6 address
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 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
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
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
iaid
]
[
preferred-lifetime
preferred-lifetime valid-lifetime
valid-lifetime
]
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 the following network parameters
in an address pool:
•
A maximum of eight DNS server addresses.
•
One domain name.
•
One address family translation router (AFTR) domain name.
•
A maximum of eight SIP server addresses.
•
A maximum of eight SIP server domain names.
You can configure network parameters on a DHCPv6 server by using one of the following methods:
•
Configure network parameters in a DHCPv6 address pool.
