Networking Requirements
As shown in Figure 1, 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.
Configuration Roadmap
The configuration roadmap is as follows:
- Enable IPv6 forwarding on the two Devices.
- Configure global unicast IPv6 addresses for interfaces.
Data Preparation
To complete the configuration, you need global unicast IPv6 addresses of the interfaces.
Procedure
- 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
- 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.
