Configuration example

By default, Ethernet, VLAN, and aggregate interfaces are shut down. You must use the undo shutdown command to bring them up. This example assumes that all these interfaces are already up.

As shown in Figure 84, configure an IPv6 over IPv4 tunnel between Switch A and Switch B so the two IPv6 networks can reach each other over the IPv4 network. Because the tunnel destination IPv4 address cannot be automatically obtained from the destination IPv6 addresses of packets, configure an IPv6 over IPv4 manual tunnel.

Make sure Switch A and Switch B have the corresponding VLAN interfaces created and can reach each other through IPv4.

• Configure Switch A:

  # Specify an IPv4 address for VLAN-interface 100.

  <SwitchA> system-view
  [SwitchA] interface vlan-interface 100
  [SwitchA-Vlan-interface100] ip address 192.168.100.1 255.255.255.0
  [SwitchA-Vlan-interface100] quit
  

  # Specify an IPv6 address for VLAN-interface 101.

  [SwitchA] interface vlan-interface 101
  [SwitchA-Vlan-interface101] ipv6 address 3002::1 64
  [SwitchA-Vlan-interface101] quit
  

  # Configure an IPv6 over IPv4 manual tunnel interface tunnel 0.

  [SwitchA] interface tunnel 0 mode ipv6-ipv4
  

  # Specify an IPv6 address for the tunnel interface.

  [SwitchA-Tunnel0] ipv6 address 3001::1/64
  

  # Specify VLAN-interface 100 as the source interface of the tunnel interface.

  [SwitchA-Tunnel0] source vlan-interface 100
  

  # Specify the destination address for the tunnel interface as the IP address of the VLAN-interface 100 on Switch B.

  [SwitchA-Tunnel0] destination 192.168.50.1
  [SwitchA-Tunnel0] quit
  

  # Configure a static route destined for IPv6 network 2 through tunnel 0 on Switch A.

  [SwitchA] ipv6 route-static 3003:: 64 tunnel 0
  

• Configure Switch B:

  # Specify an IPv4 address for VLAN-interface 100.

  <SwitchB> system-view
  [SwitchB] interface vlan-interface 100
  [SwitchB-Vlan-interface100] ip address 192.168.50.1 255.255.255.0
  [SwitchB-Vlan-interface100] quit
  

  # Specify an IPv6 address for VLAN-interface 101.

  [SwitchB] interface vlan-interface 101
  [SwitchB-Vlan-interface101] ipv6 address 3003::1 64
  [SwitchB-Vlan-interface101] quit
  

  # Configure an IPv6 over IPv4 manual tunnel interface tunnel 0.

  [SwitchB] interface tunnel 0 mode ipv6-ipv4
  

  # Specify an IPv6 address for the tunnel interface.

  [SwitchB-Tunnel0] ipv6 address 3001::2/64
  

  # Specify VLAN-interface 100 as the source interface of the tunnel interface.

  [SwitchB-Tunnel0] source vlan-interface 100
  

  # Specify the destination address for the tunnel interface as the IP address of VLAN-interface 100 of Switch A.

  [SwitchB-Tunnel0] destination 192.168.100.1
  [SwitchB-Tunnel0] quit
  

  # Configure a static route destined for IPv6 network 1 through tunnel 0 on Switch B.

  [SwitchB] ipv6 route-static 3002:: 64 tunnel 0
  

# Use the display ipv6 interface command to display tunnel interface status on Switch A and Switch B. The output shows that the interface tunnel 0 is up. (Details not shown.)

# Verify that Switch B and Switch A can ping the IPv6 address of VLAN-interface 101 of each other. For example, ping the IPv6 address of VLAN-interface 101 on Switch B from Switch A.

[SwitchA] ping ipv6 3003::1
