Configuring an IPv4 over IPv4 tunnel

Configuration prerequisites

Configure an IP addresses for the interface (such as a VLAN interface or loopback interface) to be
configured as the source interface of the tunnel interface.

Configuration guidelines

Follow these guidelines when you configure an IPv4 over IPv4 tunnel:
Specify public addresses or interfaces as the source and destination addresses for the tunnel
•
interfaces.
• 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 output
interface or specify the IPv4 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.
The IPv4 address of the local tunnel interface cannot be on the same subnet as the destination
•
address configured on the tunnel interface.
• The destination address of the route passing the tunnel interface must not be on the same subnet as
the destination address configured on the tunnel interface.
Two or more local 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 a tunnel interface, the source
•
address of the tunnel is the primary IP address of the source interface.

Configuration procedure

To configure an IPv4 over IPv4 tunnel:
Step
1. Enter system view.
2. Enter tunnel interface
view.
3. Configure
address for the tunnel
interface.
Command
system-view
interface tunnel number
an IPv4
ip address ip-address { mask |
mask-length } [ sub ]
Remarks
N/A
N/A
By default, no IPv4 address is
configured for the tunnel interface.
