Configuring an IPv4 over IPv4 tunnel

Follow these guidelines when you configure an IPv4 over IPv4 tunnel:
•
The tunnel destination address specified on the local device must be identical with the tunnel
source address specified on the tunnel peer device.
•
Do not specify the same source and destination addresses for local tunnel interfaces in the
same tunnel mode.
•
The IPv4 address of the local tunnel interface cannot be on the same subnet as the destination
address configured on the tunnel interface.
•
To ensure correct packet forwarding, identify whether the destination IPv4 network and the IPv4
address of the local tunnel interface are on the same subnet. If they are not, configure a route
reaching the destination IPv4 network through the tunnel interface. You can configure the route
by using one of the following methods:
Configure a static route, and specify the local tunnel interface as the egress interface or
specify the IPv4 address of the peer tunnel interface as the next hop.
Enable a dynamic routing protocol on both tunnel interfaces to achieve the same purpose.
For more information about route configuration, see Layer 3—IP Routing Configuration Guide.
•
The destination address of the route passing the tunnel interface cannot be on the same subnet
as the destination address configured on the tunnel interface.
To configure an IPv4 over IPv4 tunnel:
Step
1. Enter system view.
2. Enter IPv4 over IPv4 tunnel
interface view.
3. Configure an IPv4 address
for the tunnel interface.
4. Configure a source address
or source interface for the
tunnel interface.
5. Configure a destination
address for the tunnel
interface.
Command
system-view
interface tunnel number [ mode
ipv4-ipv4 ]
ip address ip-address { mask |
mask-length } [ sub ]
source { ip-address |
interface-type interface-number }
destination ip-address

Remarks
N/A
N/A
By default, no IPv4 address is
configured for the tunnel interface.
By default, no source address or
source interface is configured for
the tunnel interface.
The specified source address or
the IPv6 address of the specified
source interface is used as the
source IP address of tunneled
packets.
By default, no destination address
is configured for the tunnel
interface.
The tunnel destination address
must be the IP address of the
receiving interface on the tunnel
peer. It is used as the destination
IP address of tunneled packets.
