Command Remarks
5. Configure static or
dynamic prefix
assignment.
• Configure a static prefix binding:
static-bind prefix prefix/prefix-len
duid duid [ iaid iaid ]
[ preferred-lifetime
preferred-lifetime valid-lifetime
valid-lifetime ]
• Apply the prefix pool to the
address pool:
prefix-pool prefix-pool-number
[ preferred-lifetime
preferred-lifetime valid-lifetime
valid-lifetime ]
Use at least one command.
By default, no static or dynamic prefix
assignment is configured for an address
pool.
Configuring IPv6 address assignment
Use one of the following methods to configure IPv6 address assignment:
• Configure a static IPv6 address binding in an address pool
If you bind a DUID and an IAID to an IPv6 address, the DUID and IAID in a request must match
those in the binding before the DHCPv6 server can assign the IPv6 address to the requesting
DHCPv6 client. If you only bind a DUID to an IPv6 address, the DUID in a request must match the
DUID in the binding before the DHCPv6 server can assign the IPv6 address to the requesting client.
• Specify a subnet and address ranges in an address pool
{ Non-temporary address assignment—The server selects addresses from the non-temporary
address range specified by the address range command. If no non-temporary address range is
specified, the server selects addresses on the subnet specified by the network command.
{ Temporary address assignment—The server selects addresses from the temporary address
range specified by the temporary address range command. If no temporary address range is
specified in the address pool, the DHCPv6 server cannot assign temporary addresses to clients.
Configuring non-temporary IPv6 address assignment
Follow these guidelines when you configure non-temporary IPv6 address assignment:
• To configure multiple static IPv6 address bindings, use the static-bind address command
repeatedly.
• An IPv6 address can be bound to only one DHCPv6 client. You cannot use the static-bind address
command to modify the DUID, IAID, preferred lifetime and valid lifetime of a static IPv6 address
binding. To do so, you must remove the static binding first.
• You cannot use the network command to configure the same subnet in different address pools.
• In the same address pool, the temporary address range and address range cannot overlap.
To configure non-temporary IPv6 address assignment:
