Configuration Procedure; Configuring Ipv6 Address Assignment - HP 5920 Series Configuration Manual

Only one prefix pool can be applied to an address pool. You cannot modify prefix pools that have
•
been applied. To change the prefix pool for an address pool, you must remove the prefix pool
application first.
• You can apply a prefix pool that has not been created to an address pool. The setting takes effect
after the prefix pool is created.

Configuration procedure

To configure IPv6 prefix assignment:
Step
1. Enter system view.
2. (Optional.) Specify the
IPv6 prefixes excluded
from dynamic
assignment.
3. Create a prefix pool.
4. Create a DHCPv6
address pool and enter
its view.
5. Specify an IPv6 subnet
for dynamic assignment.
6. Configure static or
dynamic prefix
assignment.

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 client.
Command
system-view
ipv6 dhcp server forbidden-prefix
start-prefix/prefix-len
[ end-prefix/prefix-len ]
ipv6 dhcp prefix-pool prefix-pool-number
prefix prefix/prefix-len assign-len
assign-len
ipv6 dhcp pool pool-name
network prefix/prefix-length
[ preferred-lifetime preferred-lifetime
valid-lifetime valid-lifetime ]
•
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 ]

Remarks
N/A
By default, no IPv6 prefixes in the
prefix pool are excluded from
dynamic assignment.
If the excluded IPv6 prefix is in a
static binding, the prefix still can
be assigned to the client.
To exclude multiple IPv6 prefix
ranges, repeat this step.
This step is required for dynamic
prefix assignment.
By default, no prefix pool is
configured.
By default, no DHCPv6 address
pool is configured.
By default, no IPv6 subnet is
specified for dynamic
assignment.
Use at least one command.
By default, no static or dynamic
prefix assignment is configured
for an address pool.
To add multiple static IPv6 prefix
bindings, use the static-bind
prefix command.
