Configuration procedure
Make sure the corresponding VLAN interfaces have been created on the switch.
Make sure VLAN-interface 101 on the ISATAP switch and the ISATAP host can reach each other through
IPv4.
• Configure the switch:
# Specify an IPv6 address for VLAN-interface 100.
<Switch> system-view
[Switch] interface vlan-interface 100
[Switch-Vlan-interface100] ipv6 address 3001::1/64
[Switch-Vlan-interface100] quit
# Specify an IPv4 address for VLAN-interface 101.
[Switch] interface vlan-interface 101
[Switch-Vlan-interface101] ip address 1.1.1.1 255.0.0.0
[Switch-Vlan-interface101] quit
# Create service loopback group 1 and specify its service type as tunnel.
[Switch] service-loopback group 1 type tunnel
# Assign Ten-GigabitEthernet 1/0/3 to service loopback group 1.
[Switch] interface Ten-GigabitEthernet 1/0/3
[Switch-Ten-GigabitEthernet1/0/3] port service-loopback group 1
[Switch-Ten-GigabitEthernet1/0/3] quit
# Configure an ISATAP tunnel interface tunnel 0.
[Switch] interface tunnel 0 mode ipv6-ipv4 isatap
# Configure an ISATAP address for the tunnel interface tunnel 0.
[Switch-Tunnel0] ipv6 address 2001::5efe:0101:0101 64
# Specify VLAN-interface 101 as the source interface of the tunnel interface.
[Switch-Tunnel0] source vlan-interface 101
# Disable RA suppression so that the ISATAP host can acquire information such as the address
prefix from the RA message advertised by the ISATAP switch.
[Switch-Tunnel0] undo ipv6 nd ra halt
[Switch-Tunnel0] quit
# Configure a static route to the ISATAP host.
[Switch] ipv6 route-static 2001:: 16 tunnel 0
• Configure the ISATAP host:
Configurations on the ISATAP host vary depending on the operating system. The following
example is performed on Windows XP.
# Install IPv6.
C:\>ipv6 install
# On a host running Windows XP, 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, view the ISATAP interface information:
C:\>ipv6 if 2
