7. Consider the SDN OpenFlow network shown in Figure 4. Suppose that the desired forwarding behav- ior for datagrams at s3 is as follows: any datagrams arriving on input port 4 from hosts h3 or h4 that are destined to hosts h1 or h2 should be forwarded over output port 3; any datagrams arriving on input port 3 from hosts h1 or h2 that are destined to hosts h3 or h4 should be forwarded over output port 4; any arriving datagrams on input port 3 and destined to hosts h5 or h6 should be delivered to the host specified: any datagram sent by host h5 should be sent to host h6, and vice versa. Specify the flow table entries in s3 that implement this forwarding behavior. You may use wildcards to combine entries if that is possible, e.g., for hosts h3 and h4, you can combine their addresses 0.2.0.3 and 10.2.0.4 to 10.2.0.*
