Since the lower layers are short-circuited, sending to a loopback address allows the higher layers (IP and above) to be effectively tested without the chance of problems at the lower layers

Routers 2 through 5 are access routers that each have several incoming asynchronous (or ISDN) connections. Such as when sending the initial DHCPDISCOVER packet when using DHCP.
