Scenario 2: Network host config

The following figure shows the network devices on the network host for the second scenario.

The main difference between the configuration in this scenario and the previous one is the organization of the network namespaces, in order to provide isolation across the two subnets, as shown in the following figure.

In this scenario, there are four network namespaces (qhdcp-aaa, qrouter-bbbb, qrouter-cccc, and qhdcp-dddd), instead of three. Since there is no connectivity between the two networks, and so each router is implemented by a separate namespace.
