[ndnSIM] How to cache data in leafNode without request?

[m18813192770]

I build the scenario in a special environment where some Regularly updated information such as the Weather(called the first information)  is needed by all the consumers and other infomation is not. So, I want the first information pre-loading to reduce the delay. But I don't know how to do in the ndnSIM.

what I do not understand is why you want the data cached at edges but not in the middle — NDN routers cache data packets as side effect of forwarding them. 
If you dont want in-network caching, maybe you’d consider using an IP simulator?
