I tested the config through lab, it seems to work. Just like others
pointed to, there was issue before router rip betweening R1 and sw1,
because, R1 was sending unicast dhcp-offers to 129.1.3.7, but it didn't have
that route. So it had no-where to send. After turning on rip, it starts
working. Here is the configuration and the debug output.
