Hi Softwirers，
    There are some softwire technologies already in the WG, and generally,
there also need some accompanying documents to help the primary technology
be implemented flawlessly.
    So far, there are some primary documents, DHCP Option documents and 
RADIUS Option documents shown as below.
    As can be seen from the chart, softwire-multicast series is not 
complete. 
These documents all had been adopted as WG doc or became RFCs except 
draft-
hu-softwire-multicast-radius-ext-05.

+---------------------+------------------------+------------------------+

    draft-ietf-softwire-multicast-prefix-option & 
draft-hu-softwire-multicast-
radius-ext are companion documents. The former provides a method to carry
"IPv4-Embedded Multicast and Unicast IPv6 Prefixes" as a DHCPv6 option. 
Likewise
draft-hu-softwire-multicast-radius-ext provides a RADIUS option to carry 
the
above attributes.

    Is there anyone intereted in this topic? Any comments are welcome.

Thanks,
Wei
