For lab $3$B$,$ we're going to use Packet Tracer to create a small network consisting of one router with $4$ network interfaces. To do this you will need to use packet tracer to add interfaces to the router. Remember to shut down the router before adding interfaces.

The $4$ networks to be added are:

$172\mathrm{.}12.\frac{14\mathrm{.}0}{27}$

$172\mathrm{.}12,\frac{14\mathrm{.}32}{28}$

$172\mathrm{.}12.\frac{14\mathrm{.}48}{28}.$

Lets add a $/30$ network as our $4$th network, $192\mathrm{.}168\mathrm{.}223\mathrm{.}80/30.$

The network diagram shows the exact addresses to be added to the router. Normally they are network address $+1$ but the original creator of this problem wants you to know that this is not always the case. Apply the correct IP address to the network facing the Internet and apply a proper default route to the router.
