<p>Hi Obaid,</p>
<p><br>
</p>
<p>What's the data freshness period (if not set, it is set to 0 ms by default after this issue was implemented: <a href="https://redmine.named-data.net/issues/3944" class="m_-5157383704257596821OWAAutoLink" id="m_-5157383704257596821LPlnk268684" target="_blank">https://redmine.<wbr>named-data.net/issues/3944</a>)?</p>
<p>(Assuming must be fresh is set on the interest, content store will not answer).</p>

<div class="gmail_default" style="font-family:arial,helvetica,sans-serif">Hello all,
<br>
<br>
</div>
<div class="gmail_default" style="font-family:arial,helvetica,sans-serif">I am observing some strange forwarding behaviour of NFD. I am working on a star topology of 4 nodes (1 middle and three leaf nodes) where each node is running NFD and the routing is setup
in a way that the leaf nodes talk to each other via middle node. <br>
In this particular scenario two nodes (attached to face 333 and 273) requesting the same data from the third node.<br>
Here is what I am observing at the middle node. <br>
</div>
<div class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br>
</div>
<div class="gmail_default" style="font-family:arial,helvetica,sans-serif">At 1 the middle node got the interest from node 1 and as there was no matching Content in CS, it was forwarded to the Producer.
<br>
</div>
<div class="gmail_default" style="font-family:arial,helvetica,sans-serif">At 4 the middle node got the data back, which is forwarded towards the consumer in step 6.<br>
</div>
<div class="gmail_default" style="font-family:arial,helvetica,sans-serif">At 8, the middle node got the same interest from node 2. However, instead of serving it from the CS; the interest was forwarded to the Producer again.
<br>
</div>
<div class="gmail_default" style="font-family:arial,helvetica,sans-serif">Shouldn't it be served from the CS as we have already got the data in step 4. Any idea what's going wrong here?
