Configuring IPv4 over
IPv4 Tunnel
Configuration
Prerequisites

Configuration Procedure

# A link-local address (fe80::5efe:2.1.1.2) in the ISATAP format is automatically
generated for the ISATAP interface. Configure an IPv4 address for the ISATAP
router on the ISATAP interface.
C:\>ipv6 rlu 2 2.1.1.1
After carrying out the above command, look at the information on the ISATAP
interface.
C:\>ipv6 if 2
Interface 2: Automatic Tunneling Pseudo-Interface

# By comparison, it is found that the host acquires the address prefix 2001::/64
and automatically generates the address 2001::5efe:2.1.1.2. Meanwhile, "uses
Router Discovery" is displayed, indicating that the router discovery function is
enabled on the host. At this time, ping the IPv6 address of the tunnel interface of
the router. If the address is successfully pinged, an ISATAP tunnel is established.
Configuration verification
After the above configuration, the ISATAP host can access the host in the IPV6
network.
IP addresses are configured for interfaces such as VLAN interface, Ethernet
interface, and loopback interface on the device so that they can communicate.
These interfaces serve as the source interface of the tunnel to ensure that the
tunnel destination address is reachable.
Follow these steps to configure an IPv4 over IPv4 tunnel:
To do...
Enter system view
Create a tunnel interface and
enter tunnel interface view

Configuring IPv4 over IPv4 Tunnel

Use the command...
system-view
interface tunnel number
717
Remarks
-
Required
By default, there is no tunnel
interface on the device.
