Huaimo - Thanx for providing the inspiration for advertising LEEF. The draft is very explicit in saying that LEEF advertisements are for diagnostic purposes only and do NOT alter dynamic flooding state. I think there are good reasons for this. Consider the possibilities when advertised LEEF

One may observe that the draft implicitly also supports already option A too. If leader advertises full topology wouldn't it effectively disable dynamic flooding automatically ? At least no NMS or configuration push is required on all 1000s of nodes to go back to full flooding say for the purpose
