Configuration example
Network requirements
As shown in Figure 89 , configure an ISATAP tunnel between the switch and the ISATAP host so the ISATAP
host in the IPv4 network can access the IPv6 network.

Configuration procedure
1. Configure the switch:
# Specify an IPv6 address for VLAN-interface 100.
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 GigabitEthernet 1/0/3 to service loopback group 1.
[Switch] interface GigabitEthernet 1/0/3
[Switch-GigabitEthernet1/0/3] port service-loopback group 1
[Switch-GigabitEthernet1/0/3] quit
# Create the ISATAP tunnel interface Tunnel 0.
[Switch] interface tunnel 0 mode ipv6-ipv4 isatap
# Specify an EUI-64 IPv6 address for the tunnel interface tunnel 0.
[Switch-Tunnel0] ipv6 address 2001:: 64 eui-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
2. Configure the ISATAP host:
IPv6 network
Vlan-int101
1.1.1.1/8 Vlan-int100
3001::1/64
Switch
ISATAP switch
IPv6 host ISATAP host
IPv4 address: 1.1.1.2/32
IPv6 address:
FE80::5EFE:0101:0102
2001::5EFE:0101:0102 3001::2/64
IPv4 network
Tunnel0
2001::5EFE:0101:0101/64
ISATAP tunnel
Service loopback port
