$1.$ Set up the following topology in packet tracer.

$2.$ We will now configure the router by entering some basic commands $($we will do more programming of the router is future labs$).$

Click on the router and then go to the cli tab, type $$no$$ when asked to $$continue with configuration dialog$,$ then hit return on your keyboard. Enter the following commands as $($in the image below$)$ by placing the cursor after the $$Router$>$ and type $$en$,$ then hit return and so on$....$

You should have received this error

Why was this error produced?

What is the valid host range for the $255\mathrm{.}255\mathrm{.}255\mathrm{.}248$ subnet?

$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

$3.$ Now accounting for the valid host range, enter in the correct commands for this scenario$$s router

N$.$B The $$no shutdown$$ command turns on the router interface

$4.$ Your topology should be entirely connected with all ports up $($all green$)$ at this point

$5.$ Configure PCs $04$ incrementally starting with the IP address $172\mathrm{.}24\mathrm{.}59\mathrm{.}2($subnet mask of $255\mathrm{.}255\mathrm{.}255\mathrm{.}248$ for all PCs$)$

$6.$ Now try to configure PC$05$s IP address with $172\mathrm{.}24\mathrm{.}59\mathrm{.}7,$ why won$$t Packet Tracer allow you to set this IP address?

$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

$7.$ What is the usable host range for $172\mathrm{.}24\mathrm{.}59\mathrm{.}0255\mathrm{.}255\mathrm{.}255\mathrm{.}248?$

$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

$8.$ You should have realized that $172\mathrm{.}24\mathrm{.}59\mathrm{.}7$ is the broadcast address for this subnet mask and is outside of the usable host range.

It is critical to understand which subnet mask will work best for the IP addresses you will be assigning in a network, and to realize that your choice matters when it comes to efficiently utilizing IP addresses.

$9.$ You should be able to ping any other computers with an IP address in the usable host range for this subnet mask at this point

Attach a screenshot of a ping to any computer in this this network to verify connectivity and understanding of usable host ranges
