Example for Configuring IPv6 Addresses for Interfaces

Networking Requirements

In Figure 1, GE0/0/1 of SwitchA connects to GE0/0/1 of SwitchB. The two interfaces correspond to their VLANIF interfaces (VLANIF 100). You need to configure IPv6 addresses for the VLANIF interfaces and check the Layer 3 interconnection between the interfaces.

IPv6 addresses for the VLANIF interfaces are fc00:1::1/64 and fc00:1::2/64.

Configuration Roadmap

The configuration roadmap is as follows:

Enable the IPv6 forwarding function on SwitchA and SwitchB.
Configure IPv6 addresses for the interfaces.

Procedure

Enable the IPv6 forwarding function on switches.

# Configure SwitchA.

<HUAWEI> system-view
[HUAWEI] sysname SwitchA
[SwitchA] ipv6

# Configure SwitchB.

<HUAWEI> system-view
[HUAWEI] sysname SwitchB
[SwitchB] ipv6

Configure IPv6 addresses for the interfaces.

# Configure SwitchA.

[SwitchA] vlan 100
[SwitchA-vlan100] quit
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] port link-type hybrid
[SwitchA-GigabitEthernet0/0/1] port hybrid pvid vlan 100
[SwitchA-GigabitEthernet0/0/1] port hybrid untagged vlan 100
[SwitchA-GigabitEthernet0/0/1] quit
[SwitchA] interface vlanif 100
[SwitchA-Vlanif100] ipv6 enable
[SwitchA-Vlanif100] ipv6 address fc00:1::1/64
[SwitchA-Vlanif100] quit

# Configure SwitchB.

[SwitchB] vlan 100
[SwitchB-vlan100] quit
[SwitchB] interface gigabitethernet 0/0/1
[SwitchB-GigabitEthernet0/0/1] port link-type hybrid
[SwitchB-GigabitEthernet0/0/1] port hybrid pvid vlan 100
[SwitchB-GigabitEthernet0/0/1] port hybrid untagged vlan 100
[SwitchB-GigabitEthernet0/0/1] quit
[SwitchB] interface vlanif 100
[SwitchB-Vlanif100] ipv6 enable
[SwitchB-Vlanif100] ipv6 address fc00:1::2/64
[SwitchB-Vlanif100] quit

Verify the configuration.

# Check interface information on SwitchA.

# Ping the IPv6 address of SwitchB from SwitchA.

[SwitchA] ping ipv6 FC00:1::2
  PING FC00:1::2 : 56  data bytes, press CTRL_C to break
