This wording seems clumsy to me. How about: If no Router Advertisements are recieved within (NN seconds?) of joining a link and sending a Router Solicitation, IPv6 hosts that implement DHCPv6 should attempt to use DHCPv6 to obtain both IPv6 address(es) and other configuration information. [Do we need to say what happens if a router advertisement is received later?] Upon receipt of a router advertisement with the 'M' flag set (see section 5.5.3 of RFC 2462), IPv6 hosts that implement DHCPv6 MUST attempt to use DHCPv6 to obtain both IPv6 addess(es) and other configuration information. > to: > > IPv6 Nodes (acting as hosts) that implement DHCP, MUST use > DHCP upon > the receipt of a Router Advertisement with the 'O' flag set (see > section 5.5.3 of RFC2462).

Furthermore, in the absence of > a router, these types of node are not required to initiate DHCP. Similarly, how about: "Upon reciept of a Router Advertisement with the 'O' flag set (see section 5.5.3 of RFC 2462), IPv6 hosts that implement DHCPv6 MUST attempt to use DHCPv6 to obtain non-address configuration information, but not IPv6 address(es). IPv6 nodes that do not implement DHCPv6 client functionality should ignore the 'M' and 'O' bits of the router advertisement." The no router case shouldn't be repeated here, as it is covered above. And, yes, I do think that hosts should attempt to use DHCPv6 to get IPv6 addresses in the absence of a router. Also, I think it is silly to say that hosts that don't implement DHCPv6 don't need to use it... -------------------------------------------------------------------- IETF IPv6 working group mailing list [EMAIL PROTECTED] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
