== 4.  Configure and Initialize ==


Now that you have reserved your resources, you are ready to test network connectivity.

=== 4.1 Login to nodes ===
   a. Log into one of the `host` nodes (e.g. `host-1`) using `ssh`.

== 5.  Execute Experiment ==

=== 5.1 Test connectivity ===
Verify the IP connectivity between the nodes. 
 [[Image(General2.png, width=500)]]
   a. Ping various nodes shown in the picture.
{{{
ping 10.100.1.1
ping 10.100.2.2
}}} 
 

=== 5.2 Configure Server Node using a Configuration Management System (optional) ===
   a. Configure the server node and test connectivity within the whole topology by following the steps in the [wiki:GEC21Agenda/ScalingUp/Procedure/Appendix Appendix]
== 6.  Analyze Experiment ==

Now is when you would ordinarily analyze the results of your experiment.

=== 6.1 Logout of your nodes ===
 * Then type `exit` in your open terminal.
