Practice with commands

Fill in the following table:

What are the MAC and IP addresses that allspice will use to ping the serial 1 interface on chives?

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.

Questions

Did you avoid subnet zero? Remember, CCNA looks for classful addressing

Why are there only two network statements on allspice?
