Network requirements
As shown in
, Switch A is a 6to4 switch, and 6to4 addresses are used on its IPv6 network.
Switch B acts as a 6to4 relay switch and is connected to the IPv6 network (2001::/16). Configure a 6to4
tunnel between Switch A and Switch B to make Host A and Host B reachable to each other.
Figure 91 Network diagram
Configuration procedure
Make sure Switch A and Switch B have the corresponding VLAN interfaces created and can reach each
other.
Configuration on a 6to4 relay switch is similar to that on a 6to4 switch. However, to enable
communication between the 6to4 network and the IPv6 network, you must configure a route to the IPv6
network on the 6to4 switch.

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 2.1.1.1 255.255.255.0
[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
# Configure a 6to4 tunnel.
[SwitchA] interface tunnel 0
[SwitchA-Tunnel0] ipv6 address 2002:0201:0101::1/64
[SwitchA-Tunnel0] source vlan-interface 100
[SwitchA-Tunnel0] tunnel-protocol ipv6-ipv4 6to4
[SwitchA-Tunnel0] quit
# Configure a static route to the 6to4 relay.
[SwitchA] ipv6 route-static 2002:0601:0101:: 64 tunnel 0
# Configure a default route to the IPv6 network.
[SwitchA] ipv6 route-static :: 0 2002:0601:0101::1
