Enabling the DHCPv6 Server Function

Enabling the DHCPv6 Server Function

Context

If you enable the DHCPv6 server function on the interface connected to DHCPv6 clients and specify the IPv6 address pool, the device assigns IPv6 addresses or other configuration parameters, such as the DNS server address, to the clients from the IPv6 address pool bound to the interface after receiving DHCPv6 Request packets sent by the clients.

  • If a DHCPv6 server and a client reside on the same link, that is, a DHCPv6 relay agent does not exist, the device can assign the IPv6 address or other configuration parameters, such as the DNS server address, to the client attached to the interface of the DHCPv6 server.
  • If a DHCPv6 server and a DHCPv6 client reside on different links, that is, a DHCPv6 relay agent relays DHCPv6 messages between the server and client, the device can assign the IPv6 address or other configuration parameters, such as the DNS server address, to the client through the relay agent.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

  4. Run ipv6 address { ipv6-address prefix-length |ipv6-address/prefix-length }

    A global unicast IPv6 address is configured on the interface.

    By default, no global unicast IPv6 address is configured on the interface.

  5. Run dhcpv6 server pool-name [ allow-hint | preference preference-value | rapid-commit | unicast ] *
