<div style="margin: 0px; font-size: 12pt; font-family: Calibri, sans-serif">"Connected" in ndn is a bit different than how it is perceived in IP.

So, when you register a new prefix at any node, other nodes in the network need to create a route towards that prefix in order to do interest-data exchange. </span></div>
<div style="margin: 0px; font-size: 12pt; font-family: Calibri, sans-serif"><span style="font-family: Calibri, sans-serif;">Now, if you are running nlsr, and if you use nlsrc to advertise a prefix, in that case, the routes towards that advertise prefix are
propagated throughout the network and no other route creation towards that prefix is needed. </span><br>

so there is no way for other nodes to reach those prefixes registered by the server, hence, you need to create a route from other nodes.</span></div>
