Configuring The Dhcpv6 Server On An Interface; Configuration Guidelines; Configuration Procedure - H3C MSR 2600 Configuration Manual

Step
3. Specify an IPv6 subnet for
dynamic assignment.
4. (Optional.) Specify a DNS
server address.
5. (Optional.) Specify a domain
name suffix.
6. (Optional.) Specify a SIP
server address or domain
name.
7. (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 serve 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.
• Only one address pool can be applied to an interface. If you use the ipv6 dhcp server apply pool
command multiple times, the most recent configuration takes effect.
