However, NFD is not aware of this change, since the best route strategy determines which should be the next hop based on its cost. I would suggest that you use another forwarding strategy, for example the ASF strategy (section 5.2.6 in the NFD developer’s guide):</div><div class=""><br class=""></div><div class=""><a href="https://named-data.net/wp-content/uploads/2016/10/ndn-0021-7-nfd-developer-guide.pdf" class="">https://named-data.net/wp-content/uploads/2016/10/ndn-0021-7-nfd-developer-guide.pdf</a></div><div class=""><br class=""></div><div class="">Thanks,</div><div class=""><br class=""><div class="">
