OTOH,oDAD (RFC 4429) has it that: * Never using an Optimistic Address as the source address of a Router Solicitation with a SLLAO. Another address, or the unspecified address, may be used, or the RS may be sent without a SLLAO. What the new ND is doing is making a superOptimistic address out of EUI-64 based addresses that would bypass even oDAD's limitations. For addresses for which there is no way to be absolutely sure that there's no dup, it still makes sense to apply oDAD.
I don't see how the additional complexity of oDAD makes anything different in 6lowpans; as I stated in an earlier email I think it is impossible to detect duplicate EUI-64's in a 6lowpan.
That will be more efficient if the draft enforces that the routers place the SLLA option in their RAs, because otherwise, the optimistic device has no way to learn the router LLA.
Good point - we need to require the inclusion of the SLLA option in RAs. Erik _______________________________________________ 6lowpan mailing list [email protected] https://www.ietf.org/mailman/listinfo/6lowpan
