Configuring The Dhcpv6 Server To Assign Ipv6 Prefixes To Dhcpv6 Clients; Configuration Guidelines; Configuration Procedure - HPE 5820X Series Configuration Manual

Step
1. Enter system view.
2. Enable the DHCPv6 server
function.
Configuring the DHCPv6 server to assign IPv6
prefixes to DHCPv6 clients
Use one of the following methods to configure the DHCPv6 server to assign an IPv6 prefix to a
DHCPv6 client:
•
Configure a static IPv6 prefix binding in an address pool—If you bind a DUID and an IAID
to an IPv6 prefix, the DUID and IAID in a request must match those in the binding before the
DHCPv6 server can assign the IPv6 prefix to the DHCPv6 client. If you only bind a DUID to an
IPv6 prefix, the DUID in the request must match the DUID in the binding before the DHCPv6
server can assign the IPv6 prefix to the DHCPv6 client.
•
Apply a prefix pool to an address pool—The DHCPv6 server dynamically assigns an IPv6
prefix from the address pool to a DHCPv6 client.

Configuration guidelines

•
You can configure multiple static IPv6 prefix bindings.
•
An IPv6 prefix can be bound to only one DHCPv6 client. You cannot use the static-bind prefix
command to modify the DUID, IAID, preferred lifetime, and valid lifetime of an existing static
IPv6 prefix binding. To do so, remove the static IPv6 prefix binding first.
•
Only one prefix pool can be applied to an address pool.
•
A nonexistent prefix pool can be applied to an address pool, but no prefix can be assigned from
the prefix pool until the prefix pool is created.
•
You cannot use the prefix-pool command to modify an applied prefix pool, and its preferred
lifetime and valid lifetime. To do so, you must remove the application of the prefix pool first.

Configuration procedure

To configure the DHCPv6 server to assign an IPv6 prefix to a DHCPv6 client:
Step
1. Enter system view.
2. Create a prefix pool.
3. Create a DHCPv6
address pool and enter
its view.
