Claim 2:
3. The method of claim 1, further comprising:
detecting by the receiving LLN device, within the one multicast data message specifying the lowest distance value, a corresponding rank of the corresponding one neighboring transmitting LLN device in a current rank field, and a rank limit in a rank limit field;
selectively limiting one or more of upward flooding or downward flooding of the multicast data message in the LLN based on a corresponding rank of the receiving LLN device relative to the current rank field and the rank limit;
wherein the rank limit identifies one or more of a minimum rank limit for limiting upward flooding to an LLN device having the minimum rank limit as its corresponding rank, or a maximum rank limit for limiting downward flooding to an LLN device having the maximum rank limit as its corresponding rank.
