Example for Configuring IPv6 Addresses for Interfaces

Example for Configuring IPv6 Addresses for Interfaces

This example shows how to configure IPv6 addresses for interfaces.

Networking Requirements

As shown in Figure 12-5, Device A and Device B are connected through GE interfaces. To check the connectivity between the two interfaces, configure global unicast IPv6 addresses 2001:db8::1/32 and 2001:db8::2/32 for the GE interfaces.

Device Name

Interface

IP Address

DeviceA

GE0/1/0

2001:db8::1/32

DeviceB

GE0/1/0

2001:db8::2/32

Precautions

None

Configuration Roadmap

The configuration roadmap is as follows:

  1. Enable IPv6 forwarding on the two Devices.

  2. Configure global unicast IPv6 addresses for interfaces.

Data Preparation

To complete the configuration, you need global unicast IPv6 addresses of the interfaces.

Procedure

  1. Configure global unicast IPv6 addresses for interfaces.

    # Configure Device A.

    <HUAWEI> system-view
    [~HUAWEI] sysname DeviceA
    [*HUAWEI] commit
    [~DeviceA] interface GigabitEthernet 0/1/0
    [~DeviceA-GigabitEthernet0/1/0] ipv6 enable
    [*DeviceA-GigabitEthernet0/1/0] ipv6 address 2001:db8::1 32
    [*DeviceA-GigabitEthernet0/1/0] undo shutdown
    [*DeviceA-GigabitEthernet0/1/0] commit
    [~DeviceA-GigabitEthernet0/1/0] quit

    # Configure Device B.

    <HUAWEI> system-view
    [~HUAWEI] sysname DeviceB
    [*HUAWEI] commit
    [~DeviceB] interface GigabitEthernet 0/1/0
    [~DeviceB-GigabitEthernet0/1/0] ipv6 enable
    [*DeviceB-GigabitEthernet0/1/0] ipv6 address 2001:db8::2 32
    [*DeviceB-GigabitEthernet0/1/0] undo shutdown
    [*DeviceB-GigabitEthernet0/1/0] commit
    [~DeviceB-GigabitEthernet0/1/0] quit

  2. Verify the configuration.

    If you can view the configured unicast global addresses and that the interfaces and the IPv6 protocol are in the Up state, it indicates that the configuration is successful.

    # Display the interface information of Device A.

    [~DeviceA] display ipv6 interface GigabitEthernet 0/1/0
    GigabitEthernet0/1/0 current state : UP
    IPv6 protocol current state : UP
    link-local address is FE80::C964:0:B8B6:1
      Global unicast address(es):
        2001:db8::1, subnet is 2001:db8::/32
      Joined group address(es):
        FF02::1:FF00:1
        FF02::1:FFB6:1
        FF02::2
        FF02::1
      MTU is 4470 bytes
      ND DAD is enabled, number of DAD attempts: 1
      ND reachable time is 1200000 milliseconds
      ND retransmit interval is 1000 milliseconds
      Hosts use stateless autoconfig for addresses

    # Display the interface information of Device B.

    [~DeviceB] display ipv6 interface GigabitEthernet 0/1/0
    GigabitEthernet0/1/0 current state : UP
    IPv6 protocol current state : UP
    link-local address is FE80::2D6F:0:7AF3:1
      Global unicast address(es):
        2001:db8::2, subnet is 2001:db8::/32
      Joined group address(es):
        FF02::1:FF00:2
        FF02::1:FFF3:1
        FF02::2
        FF02::1
      MTU is 4470 bytes
      ND DAD is enabled, number of DAD attempts: 1
      ND reachable time is 1200000 milliseconds
      ND retransmit interval is 1000 milliseconds
      Hosts use stateless autoconfig for addresses

    # Ping the link-local address of Device B from Device A. Note that you need to use the parameter -i to specify the interface corresponding to the link-local address.

    [~DeviceA] ping ipv6 fe80::2d6f:0:7af3:1 -i GigabitEthernet 0/1/0
