Configure the network according to the specifications listed in the previous section. Select the IP address for each networking device in each network segment.

Test your network carefully, and then save your configuration. All machines should be able to ping

each other. You will be asked to verify that you have configured routing to all subnets in your network.

Be sure and save the configuration; you will be asked to demonstrate your network to your

instructor.
