Configuration considerations
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 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 24
[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
# Configure a 6to4 address for the tunnel interface.
[SwitchA-Tunnel0] ipv6 address 2002:201:101::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 2002::/16 through the tunnel interface.
[SwitchA] ipv6 route-static 2002:: 16 tunnel 0
