I have some additional comments (and questions) on dhcpv6-24, particularly about server solicitation. (1) If the client sent a solicit message with a rapid commit option but the server responds to the solicitation with an advertise message, what should the client do? Should it ignore the advertise, should it accept the advertise and send a request, or others? Section 17.1.4 says ...If the client does not receive a Reply message, the client restarts the server solicitation process by sending a Solicit message that does not include a Rapid Commit option. So, the client should probably ignore the advertise (and keep waiting for a reply.) But I'm not 100% sure about this. (2) Section 17.1.2 says: If the client is waiting for an Advertise message, the mechanism in section 14 is modified as follows for use in the transmission of Solicit messages. The message exchange is not terminated by the receipt of an Advertise before IRT has elapsed. Rather, the client collects Advertise messages until IRT has elapsed. Should this rule apply if the client is retransmitting solicit messages? For example, suppose that there is no advertise in response to the first solicit, and so the client retransmit the solicit. If the client then receives a first advertise, should it still wait until IRT elapses? (3) The paragraph above then says: Also, the first RT MUST be selected to be strictly greater than IRT by choosing RAND to be strictly greater than 0. However, according to Section 13, the first RT should be RT = 2*IRT + RAND*IRT where RAND is a random number chosen with a uniform distribution between -0.1 and +0.1. Thus, RT >= 2*IRT - 0.1*IRT = 1.9 * IRT >= IRT (the rightmost '=' is satisfied only when IRT is 0) So the RT should always be greater than IRT regardless of the value of RAND, and "by choosing RAND to be strictly greater than 0" seems to be redundant. Is my understanding correct? JINMEI, Tatuya Communication Platform Lab.
