<div class="">Hi Tai-Lin,</div>

<blockquote type="cite" class="">Is this understanding correct?</blockquote>
Yes, I think you have the general idea.</div>
<div class=""><br class="">
</div>
<div class="">The CHILD_INHERIT flag, when applied to a route, allows a longer child name prefix to use that route for forwarding. It adds the route as an option to the FIB, but the route used to forward the Interest is up to the strategy. A parent prefix with
a route without the CHILD_INHERIT flag will not be added to the FIB entry for a longer prefix.</div>
<div class=""><br class="">
</div>
<div class="">CAPTURE prevents a name prefix and longer children prefixes from using a route associated with a shorter parent name prefix. The CAPTURE flag will not only prevent inheritance for the same name prefix but also longer children prefixes.</div>
<div class=""><br class="">
</div>
<div class="">
<blockquote type="cite" class="">What is the use case of capture?</blockquote>
</div>
<div class="">The capture flag can be used to prevent traffic for a prefix from flowing to another route.</div>
<div class=""><br class="">
</div>
<div class="">For example, if laptop 1 registers /A with CHILD_INHERIT and laptop 2 registers /A/B with no flags, traffic for /A/B can be forwarded to both laptop 1 and 2.</div>
<div class=""><br class="">
</div>
<div class="">If laptop 2 instead registers /A/B with the CAPTURE flag, traffic for /A/B will be forwarded to laptop 2 and will not be forwarded to laptop 1.</div>

Is this understanding correct?<br class="">
CHILD_INHERIT: true = usual lpm, false = exact matching<br class="">
CAPTURE: prevent lpm to be used (in other entries with the same name)<br class="">
