Thanks for the specific reference. Right, RFCs 2461 and 2462 say that one should only use the "stateful" configuration mechanism when the "O" bit (or the "M" bit) is set, but given that DHCPv6 Information Request is stateless (except in the sense that "stateful" is sometimes used as a euphemism for "DHCP"), I don't see the text in RFCs 2461 and 2462 as settling this one way or the other. To reiterate (briefly): the stateless/stateful distinction makes sense for address configuration. For non-address-configuration, all the protocols we're talking about are stateless. > btw - it is still unclear to me if "administered (stateful) mechanism" > mentioned in RFC2461 is DHCPv6, or some other protocol. > it is not explicitly stated anywhere. Right, DHCPv6 is cited as an example, but that's all. -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
