I think the IETF has been pretty good about keeping the information from the two sources independent. Regarding address assignment specifically, what contradictory information might be provided? I can imagine a node might get one address from SLAAC and another from DHCPv6, but that's an acceptable configuration. DHCPv6 doesn't provide prefix information, so no conflicts there. I don't think there's an issue if DHCPv6 assigns an address that's not in a prefix advertised in an RA. - Ralph > > John > > -------------------------------------------------------------------- > IETF IPv6 working group mailing list > ipv6@ietf.org > Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 > -------------------------------------------------------------------- -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
