<p>Thanks a lot. I have got the hop count in the forwarder through your hint.</p>

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

<p>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.

<div dir="auto">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. </div>

<div style="margin-top:0;margin-bottom:0">Greetings All,<br>
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:</div>
<div style="margin-top:0;margin-bottom:0"> 1. added "interest->setTag(make_shared<<wbr>lp::HopCountTag>(0));" for hopcount initialization at the function "SendPacket" in consumer.cpp;</div>
<div style="margin-top:0;margin-bottom:0"> 2. added "interest.setTag(make_shared<l<wbr>p::HopCountTag>(hopCount + 1))" for one hop increment when forwarding a time at the function "onIncomingInterest" in Forwarder.cpp.</div>
<div style="margin-top:0;margin-bottom:0"><br>
</div>
<div style="margin-top:0;margin-bottom:0">I do not know if you have a right solution to count the forwarding hops for an interest?
<br>
</div>
<div style="margin-top:0;margin-bottom:0"><br>
</div>
<div style="margin-top:0;margin-bottom:0">Thanks!</div>
