[ndnSIM] [EXT] How to limit the hop count of interest

[Shuai Dong]

Hi Junxiao,

Thanks for your reply.
I still have one more question: If I use interest.SetHopLimit(1), does that
mean the interest can only be sent from the consumer to its one-hop
neighbors, like the Time to Live(TTL)? The nodes, which receive the
interest, will not do the further process?

Thanks!
SIncerely
Shuai
