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
