More precisely, the M bit indicates that a client wishing to do stateful may do it, and the M=0 bit indicates that the client should not try. If the router wants to not enable stateless, then the M bit is not the right tool. The router should simply not advertise that prefixes are available for stateless auto-configuration. -- Christian Huitema -------------------------------------------------------------------- IETF IPv6 working group mailing list [EMAIL PROTECTED] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
