The host has acquired the address prefix 2001::/64 and has automatically generated the global
unicast address 2001::5efe:1.1.1.2. The message "uses Router Discovery" indicates that the
router discovery function is enabled on the host.

Configure the IPv6 host:
# Configure a route to the ISATAP switch.
C:\>netsh interface ipv6 set route 2001::/64 5 3001::1
Verifying the configuration
# Ping the IPv6 host from the ISATAP host. The ping operation succeeds, indicating an ISATAP tunnel has
been established.
C:\>ping 3001::2

Configuring an IPv4 over IPv4 tunnel
Follow these guidelines when you configure an IPv4 over IPv4 tunnel:
•
The destination address specified for the local tunnel interface must be the source address specified
for the peer tunnel interface, and vice versa.
•
The source/destination addresses of local tunnels of the same tunnel mode cannot be the same.
•
The IPv4 address of the local tunnel interface cannot be on the same subnet as the destination
address configured on the tunnel interface.
