   The message exchange is not terminated by the receipt of an Advertise
   before the first RT has elapsed. Rather, the client collects Advertise
   messages until the first RT has elapsed.
   Also, the first RT MUST be selected to be strictly greater than IRT
   by choosing RAND to be strictly greater than 0.
