| 206 | The <tt>ccnx-setup</tt> execute command takes as parameters the name of a single "barrier" node, which must be up in order for the experiment to start, and the number of nodes in the topology as follows: |
| 207 | <pre>ccnx-setup BARRIER_NODE NUM_NODES</pre> |
| 208 | We will continue to use the node <tt>ccnx-router</tt> as the barrier node. |
| 209 | <br/><br/> |
| 210 | We will add two nodes to the topology, so go ahead and change the number of nodes from 3 to 5. |
| 211 | The new <tt>ccnx-router</tt> execute command on <b>all three nodes</b> should be: |
| 212 | <pre>cd /tmp/ccnx-setup && ./ccnx-setup ccnx-router 5</pre> |
