Configuring a 6to4 tunnel

Configuration prerequisites

Configure IP addresses for interfaces (such as the VLAN interface, GigabitEthernet interface, and

loopback interface) on the firewall to ensure normal communication. One of the interfaces will be used

as the source interface of the tunnel.

Configuration guidelines

Follow these guidelines when you configure a 6to4 tunnel:

No destination address needs to be configured for a 6to4 tunnel because the destination address
can automatically be obtained from the IPv4 address embedded in the 6to4 IPv6 address.

To encapsulate and forward IPv6 packets whose destination address does not belong to the subnet
where the receiving tunnel interface resides, configure a static route to reach the destination IPv6
address through this tunnel interface on the firewall. Because automatic tunnels do not support

dynamic routing, you can configure a static route to that destination IPv6 address with this tunnel

interface as the outbound interface or the peer tunnel interface address as the next hop. A similar

configuration needs to be performed at the other tunnel end. For the detailed configuration, see
Network Management Configuration Guide.
