If we define the 00=No Opinion, then we may need to use 11 to convey unavailability of DHCPv6, may not be good symantics. If we agree that we need to convey 'availability', 'unavailability' and 'no opinion; then how about the following combination M O 0 0 - DHCPv6 Not avaialble 0 1 - Only DHCP6v lite 1 0 - Full DHCPv6 1 1 - No opinion (router does not know if the DHCPv6 avaialble or not) -Syam -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
