Example for Configuring IPv6 Neighbor Discovery

Example for Configuring IPv6 Neighbor Discovery

This section provides an example for configuring IPv6 neighbor discovery.

Networking Requirements

As shown in Figure 12-6, Device A is directly connected to the PC by GE 0/1/0. This PC runs the Windows XP operating system.

Figure 12-6 Configuring IPv6 neighbor discovery

Precautions

None.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure a link-local unicast address and global EUI-64 unicast addresses on GE 0/1/0.

  2. Configure the RA prefix message to be advertised on GE 0/1/0 and enable the advertisement of the RA prefix message.

Data Preparation

To complete the configuration, you need the following data:

  • Local unicast addresses of the link and global EUI-64 on GE 0/1/0

  • RA prefix message to be advertised

Procedure

  1. Configure the local unicast address of the link on GE 0/1/0. After the ipv6 enable command is run on an interface, the system automatically generates a link-local address for the interface.

    <HUAWEI> system-view
    [~HUAWEI] sysname DeviceA
    [*HUAWEI] commit
    [~DeviceA] interface gigabitethernet 0/1/0
    [~DeviceA-GigabitEthernet0/1/0] undo shutdown
    [*DeviceA-GigabitEthernet0/1/0] ipv6 enable
    [*DeviceA-GigabitEthernet0/1/0] commit

  2. Configure the local unicast address of the EUI-64 site on GE 0/1/0 and the prefix in the RA message.

    NOTE:
    A PC can automatically obtain the RA prefix message from devices only after the RA prefix message to be advertised is configured and the advertisement of the RA prefix message is enabled on devices.
    [~DeviceA-GigabitEthernet0/1/0] ipv6 address 2001:db8::/32 eui-64
    [*DeviceA-GigabitEthernet0/1/0] ipv6 nd ra prefix 2001:db8::/32 1000 1000
    [*DeviceA-GigabitEthernet0/1/0] undo ipv6 nd ra halt
    [*DeviceA-GigabitEthernet0/1/0] commit
    [~DeviceA-GigabitEthernet0/1/0] quit

  3. Verify the configuration.

    If configurations are successful, you can view the configured local unicast address of the link and the global EUI-64 and find that GE 0/1/0 is Up and IPv6 is Up.
