2 Configure 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 ISATAP interface information is as follows:
C:\>ipv6 if 2
