In the forwarder::onIncomingInterest method you can extract the interest
hop count tag the same way as in consumer::onData method.

Thank you for your reply, but can I get the hop count at the forwarder?
Because I want to stop forwarding an Interest, if its forwarding hops
exceed a certain amount.

I think that interest, as well as data packet, already has a hop count
field. If you want to get total hop count of an interest you can get it at
the producer application.

Greetings All,
Now I have a question regarding how to count the forwarding hops of an
Interest in ndnSIM. I simply added the below codes, but it seems like I
got the wrong forwarding hops:
1. added "interest->setTag(make_shared<lp::HopCountTag>(0));" for
hopcount initialization at the function "SendPacket" in consumer.cpp;
2. added "interest.setTag(make_shared<lp::HopCountTag>(hopCount + 1))" for
one hop increment when forwarding a time at the function
"onIncomingInterest" in Forwarder.cpp.
I do not know if you have a right solution to count the forwarding hops for
an interest?
Thanks!
Zhuhua
