Verifying the configuration
# Use the display interface tunnel command to display the status of the tunnel interfaces on Switch A and
Switch B. The output shows that the tunnel interfaces are up. (Details not shown.)
# Ping the IPv4 address of the peer interface VLAN-interface 100 from each switch. The following shows
the output on Switch A.
[SwitchA] ping -a 10.1.1.1 10.1.3.1

Configuring an IPv4 over IPv6 tunnel
Follow these guidelines when you configure an IPv4 over IPv6 tunnel:
• The destination address specified for the local tunnel interface must be the source address specified
for the peer tunnel interface, and vice versa.
• Two or more local tunnel interfaces using the same encapsulation protocol must have different
source and destination addresses.
• If the destination IPv4 network is not on the same subnet as the IPv4 address of the local tunnel
interface, you must configure a route destined for the destination IPv4 network through the tunnel
interface. You can configure a static route, and specify the local tunnel interface as the egress
interface or specify the IPv6 address of the peer tunnel interface as the next hop. Alternatively, you
can enable a dynamic routing protocol on both tunnel interfaces to achieve the same purpose. For
the detailed configuration, see Layer 3—IP Routing Configuration Guide.
To configure an IPv4 over IPv6 tunnel:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter tunnel interface
view.
interface tunnel number [ mode
ipv6 ]
N/A
3. Configure an IPv4
address for the tunnel
interface.
ip address ip-address { mask |
mask-length } [ sub ]
By default, no IPv4 address is configured
for the tunnel interface.
