Configuring Network Parameters In A Dhcpv6 Option Group; Configuring The Dhcpv6 Server On An Interface; Configuration Guidelines - HP FlexNetwork MSR2003 Configuration Manual

Configuring network parameters in a DHCPv6 option group

A DHCPv6 option group can be created by using the following methods:
•
Create a static DHCPv6 option group by using the ipv6 dhcp option-group command.
•
When the device acts as a DHCPv6 client, it automatically creates a dynamic DHCPv6 option
group for saving the obtained parameters. For more information about creating a dynamic
DHCPv6 option group, see
To create a static DHCPv6 option group:
Step
1. Enter system view.
2. Create a static DHCPv6
option group and enter its
view.
3. (Optional.) Specify a DNS
server address.
4. (Optional.) Specify a domain
name suffix.
5. (Optional.) Specify a SIP
server address or domain
name.
6. (Optional.) Configure a
self-defined DHCPv6 option.

Configuring the DHCPv6 server on an interface

Enable the DHCP server and configure one of the following address/prefix assignment methods on
an interface:
•
Apply an address pool on the interface—The DHCPv6 server selects an IPv6 address/prefix
from the applied address pool for a requesting client. If there is no assignable IPv6
address/prefix in the address pool, the DHCPv6 server cannot to assign an IPv6 address/prefix
to a client.
•
Configure global address assignment on the interface—The DHCPv6 server selects an
IPv6 address/prefix in the global DHCPv6 address pool that matches the server interface
address or the DHCPv6 relay agent address for a requesting client.
If you configure both methods on an interface, the DHCPv6 server uses the specified address pool
for address assignment without performing global address assignment.

Configuration guidelines

•
An interface cannot act as a DHCPv6 server and DHCPv6 relay agent at the same time.
•
Do not enable DHCPv6 server and DHCPv6 client on the same interface.
•
If you use the ipv6 dhcp server command multiple times, the most recent configuration takes
effect.
•
You can apply an address pool that has not been created to an interface. The setting takes
effect after the address pool is created.
