        Title           : An anycast prefix for 6to4 relay routers

The operation of 6to4 routers require either that participation in 
IPv6 inter-domain routing, or that the routers be provisioned with a 
default route. This memo proposes a standard method to define the 
default route. It requires that IANA assign a '6to4 Relay anycast 
prefix' from which 6to4 routers can derive the static '6to4 anycast 
address'. In order to enable efficient management of the '6to4 Relay 
anycast prefix' in IPv4 inter-domain routing, this memo also 
requests the reservation by IANA of a '6to4 Autonomous System ID.'
With this definition, the proposed scheme guarantees that 6to4 
packets will be automatically routed to the nearest available 
router. It allows the managers of the 6to4 relay routers to control 
the sources authorized to use their resource. It makes it easy to 
set up a large number of 6to4 relay routers, thus enabling 
scalability.

NOTE:   The mail server at ietf.org can return the document in
        MIME-encoded form by using the "mpack" utility.  To use this
        feature, insert the command "ENCODING mime" before the "FILE"
        command.  To decode the response(s), you will need "munpack" or
        a MIME-compliant mail reader.  Different MIME-compliant mail readers
        exhibit different behavior, especially when dealing with
        "multipart" MIME messages (i.e. documents which have been split
        up into multiple messages), so check your local documentation on
        how to manipulate these messages.
