The configuration on a 6to4 relay switch is similar to that on a 6to4 switch. To enable communication
between the 6to4 network and the IPv6 network, configure a route destined for the IPv6 network on the
6to4 switch.

Configuration procedure
Make sure Switch A and Switch B have the corresponding VLAN interfaces created and can reach each
other through IPv4.
• Configure Switch A:
# Configure an IPv4 address for VLAN-interface 100.
system-view
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] ip address 2.1.1.1 255.255.255.0
[SwitchA-Vlan-interface100] quit
# Configure a 6to4 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 a 6to4 tunnel interface tunnel 0.
[SwitchA] interface tunnel 0 mode ipv6-ipv4 6to4
# Create a 6to4 address for the tunnel interface.
[SwitchA-Tunnel0] ipv6 address 2002:0201:0101::1/64
# Specify the source interface as VLAN-interface 100 for the tunnel interface.
[SwitchA-Tunnel0] source vlan-interface 100
[SwitchA-Tunnel0] quit
# Configure a static route destined for the 6to4 relay switch.
[SwitchA] ipv6 route-static 2002:0601:0101:: 64 tunnel 0
# Configure a default route to reach the IPv6 network, which specifies the address of the interface
tunnel 0 of the 6to4 relay switch as the next hop.
[SwitchA] ipv6 route-static :: 0 2002:0601:0101::1
• Configure Switch B:
# Configure an IPv4 address for VLAN-interface 100.
