Uhh, this seems like a total abuse of the RA mechanism :-). The point of it to be able to carry the prefixes needed for autoconfiguration. If it's supposed to be used for a beacon mechanism, I'd suggest considering whether one could find a method that does not send prefixes at ALL (or, just send the prefix of the router with prefixlen=128 if you really insist). This would enable you to retain the model where RA's would in fact be complete when they included prefix information options that the nodes would use. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
