Could you cite where exactly this is stated in the RFC documents? (Would save me the time to dig through all the RFCs to find that particular statement and help avoid misunderstanding.) It appears to me to be a contradiction in terms. IPv6 interfaces must be able to have several IP addresses, and IPv6 does not have a default route (or 0::0/0). IPv6 interfaces are designed to participate in multiple independend logical networks (and several address ranges have been reserved for future extensions and uses). It therefore does not make sense if autoconfiguration for one network and routing for another are mutually exclusive. I'd like to check this (and maybe file a bug in the RFC). regards Hadmut
