Example for Configuring a DHCPv6 PD Client

Example for Configuring a DHCPv6 PD Client

Networking Requirements

In Figure 9-19, the industrial switch router is required to function as a DHCPv6 PD client and obtain an IPv6 address prefix from the DHCPv6 PD server. Configure the industrial switch router as a DHCPv6 PD client to assign IPv6 addresses and other network configuration parameters to DHCPv6 clients. This reduces pressure on the DHCPv6 server and facilitates layered IPv6 network deployment. The address of the DHCPv6 PD server is fc00:1::1/64. The DHCPv6 PD server and client are on the same link.

Configuration Roadmap

The configuration roadmap is as follows:
  1. Enable IPv6 functions on the interface so that devices can communicate using IPv6.

  2. Enable the DHCPv6 PD client function so that devices can obtain IPv6 address prefixes using DHCPv6.

Procedure

  1. Enable the DHCP service.

    <Huawei> system-view
    [Huawei] sysname Router A
    [Router A] dhcp enable

  2. Configure IPv6 functions on an interface.

    [Router A] ipv6
    [Router A] interface gigabitethernet 0/0/1
    [Router A-GigabitEthernet0/0/1] undo portswitch
    [Router A-GigabitEthernet0/0/1] ipv6 enable
    [Router A-GigabitEthernet0/0/1] ipv6 address auto link-local

  3. Enable the DHCPv6 PD client function.

    # Enable the DHCPv6 PD client function on GE0/0/1.

    [Router A-GigabitEthernet0/0/1] dhcpv6 client pd myprefix 
    [Router A-GigabitEthernet0/0/1] quit 
    

  4. Configure Router A to send an RA message to assign address prefixes to hosts.

    # Configure the device to send RA messages and configure M and O flag bits.

    [Router A] interface gigabitethernet 0/0/2
    [Router A-GigabitEthernet0/0/2] undo portswitch
    [Router A-GigabitEthernet0/0/2] ipv6 enable
    [Router A-GigabitEthernet0/0/2] ipv6 address auto link-local
    [Router A-GigabitEthernet0/0/2] undo ipv6 nd ra halt 
    [Router A-GigabitEthernet0/0/2] ipv6 nd autoconfig other-flag
    [Router A-GigabitEthernet0/0/2] ipv6 address myprefix ::1:0:0:0:1/64  
    [Router A-GigabitEthernet0/0/2] quit

  5. Verify the configuration.

    # Run the display dhcpv6 client command on the Router A to check the DHCPv6 client configurations.

    <Router A> display dhcpv6 client
    GigabitEthernet0/0/1 is in DHCPv6-PD client mode.
