Configuring an IPv4 over IPv6 tunnel

Configuration prerequisites

Configure IP addresses for interfaces (such as the VLAN interface, and loopback interface) on the device
to ensure normal communication. One of the interfaces will be used as the source interface of the tunnel.

Configuration guidelines

Follow these guidelines when you configure an IPv4 over IPv6 tunnel:
Specify public addresses or interfaces as the source end destination addresses or interfaces.
•
To encapsulate and forward IPv4 packets whose destination address does not belong to the subnet
•
where the receiving tunnel interface resides, configure a static route or dynamic routing for
forwarding those packets through this tunnel interface. If you configure a static route to that
destination IPv4 address, specify this tunnel interface as the outbound interface, or the peer tunnel
interface address as the next hop. A similar configuration is required at the other tunnel end. If you
configure dynamic routing at both ends, enable the dynamic routing protocol on both tunnel
interfaces. For the detailed configuration, see Layer 3—IP Routing Configuration Guide.
Two or more tunnel interfaces using the same encapsulation protocol must have different source and
•
destination addresses.
• If you specify a source interface instead of a source address for the tunnel, the source address of the
tunnel is the primary IP address of the source interface.

Configuration procedure

To configure an IPv4 over IPv6 tunnel:
Step
1. Enter system view.
2. Enable IPv6.
3. Enter tunnel interface
view.
4. Configure an IPv4
address for the tunnel
interface.
5. Specify the IPv4 over
IPv6 tunnel mode.
Command
system-view
ipv6
interface tunnel number
ip address ip-address { mask |
mask-length } [ sub ]
tunnel-protocol ipv4-ipv6
205
Remarks
N/A
By default, the IPv6 packet forwarding
function is disabled.
N/A
By default, no IPv4 address is configured
for the tunnel interface.
GRE over IPv4 tunnel by default.
The same tunnel mode should be
configured at both ends of the tunnel.
Otherwise, packet delivery will fail.
