Configuration example

Network requirements
As shown in
(Switch A and Switch B). Configure a 6to4 tunnel to make Host A and Host B reachable to each other.
Figure 65 Network diagram
Configuration consideration
To enable communication between 6to4 networks, configure 6to4 addresses for 6to4 switches and hosts
in the 6to4 networks.
The IPv4 address of VLAN-interface 100 on Switch A is 2.1.1.1/24, and the corresponding 6to4

prefix is 2002:0201:0101::/48 after it is translated to an IPv6 address. Assign interface Tunnel 0 to
subnet 2002:0201:0101::/64 and VLAN-interface 101 to subnet 2002:0201:0101:1::/64.
• The IPv4 address of VLAN-interface 100 on Switch B is 5.1.1.1/24, and the corresponding 6to4
prefix is 2002:0501:0101::/48 after it is translated to an IPv6 address. Assign interface Tunnel 0 to
subnet 2002:0501:0101::/64 and VLAN-interface 101 to subnet 2002:0501:0101:1::/64.
Configuration procedure
Before configuring a 6to4 tunnel, make sure that Switch A and Switch B have the corresponding VLAN
interfaces created and are reachable to each other.
• Configure Switch A:
# Enable IPv6.
<SwitchA> system-view
[SwitchA] ipv6
# Configure an IPv4 address for VLAN-interface 100.
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] ip address 2.1.1.1 24
[SwitchA-Vlan-interface100] quit
# Configure an IPv6 address for VLAN-interface 101.
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] ipv6 address 2002:0201:0101:1::1/64
[SwitchA-Vlan-interface101] quit
# Create service loopback group 1 to support the tunnel service.
[SwitchA] service-loopback group 1 type tunnel
