Configuring 6to4 Relay for Non-2002 Prefix Access

By default, 6to4 auto tunnel can only access the destination with a 2002 prefix. The 6to4 relay feature can be used to access non-2002 prefix destinations. To enable 6to4 relay, simply create a Route Policy to route all traffic destined for 2003 prefixes over the 6to4 auto tunnel interface, as shown in the following example.

This static route can be added on the 6to4 auto tunnel interface to enable the relay feature, which makes it possible to access the IPv6 destination with non-2002: prefix through 6to4 tunnel. Note that, the gateway must be the IPv6 address with the 2002: prefix.
