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 the IPv4 address
of the ISATAP router on the interface to complete the configuration on the host. Before doing that,
display the ISATAP interface information:
C:\>ipv6 if 2
Interface 2: Automatic Tunneling Pseudo-Interface
