Configuration procedure
The following example shows how to configure an ISATAP tunnel between the
router and the ISATAP host, which allows a separate ISATAP host to access the IPv6
network.
Configuration on the ISATAP router
■
# Enable the IPv6 forwarding function.
<Router> system-view
[Router] ipv6
# Configure addresses for interfaces.
[Router] interface ethernet1/0
[Router-Ethernet1/0] ipv6 address 3001::1/64
[Router-Ethernet1/0] quit
[Router] interface ethernet 1/1
[Router-Ethernet1/1] ip address 2.1.1.1 255.0.0.0
[Router-Ethernet1/1] quit
# Configure an ISATAP tunnel.
[Router] interface tunnel 10
[Router-Tunnel0] ipv6 address 2001::1/64 eui-64
[Router-Tunnel0] source ethernet 1/1
[Router-Tunnel0] tunnel-protocol ipv6-ipv4 isatap
# Disable the RA suppression so that hosts can acquire information such as the
address prefix from the RA message released by the ISATAP router.
[Router-Tunnel0] undo ipv6 nd ra halt
Configuration on the ISATAP host
■
The specific configuration on the ISATAP host is related to its operating system.
The following example shows the configuration of the host running the Windows
XP.
# On a Windows XP-based host, the ISATAP interface is usually interface 2.
Configure an IPv4 address for the ISATAP router to complete the configuration on
the host. The information on the ISATAP interface is as follows:
C:\>ipv6 if 2
Interface 2: Automatic Tunneling Pseudo-Interface
