Testing Connectivity ==================== **Step 1.** Test the connectivity between namespaces h1 and h2 using the ``ping`` command.:: ip netns exec h1 ping 192.168.10.2 -c 4 .. image:: images/fig_40.jpg **Figure 40:** Output of the ``ping`` command. The figure shows successful connectivity between two namespaces. **Step 2.** Switch back to the terminal tab in which the DPDK pipeline is running. .. image:: images/fig_41.jpg **Figure 41:** Switching terminal tabs. The logs in the terminal correspond to the code executed for packet processing. **Step 1.** Stop the DPDK pipeline by pressing ``ctrl+c``. .. image:: images/fig_42.jpg **Figure 42:** Stopping the DPDK pipeline. This concludes Lab 1. You can now end your reservation.
