Do a show interface on an Ethernet interface and note the counter values. What happens if you ping to the broadcast address? Objective 2 You are told that the Ethernet in the previous example must provide address space for at least 500 hosts. A second Ethernet, shown in Figure 2, will interconnect Bay and Chives, and must have address space for no more than 126 hosts. Develop a configuration that shows appropriate subnetting. Write a configuration that reflects efficient subnetting for the two Ethernets. Serial line interfaces do not change. Provide correct ip host statements.

Remember, CCNA looks for classful addressing. Why are there only two network statements on allspice?
