IP ADDRESING AND NETWORK DESIGN

IP addressing

You have been hired by a small company to install a simple LAN for its $7$ computers denoted PC$1$ to PC$7.$ Develop in Cisco Packet Tracer a simple LAN topology which comprises $1$ router and $3$ switches. Computers PC$1$ and PC$2$ are connected to switch Nr$.1,$ PC$3$ and PC$4$ to switch Nr$.2,$ and PC$5-$PC$7$ to Nr$.3.$ Switches Nr$\mathrm{.}2$ & $3$ are connected through the router.

$-$ Use the network $192\mathrm{.}168\mathrm{.}20\mathrm{.}0/24$ to connect and

The gateway IP is: $192\mathrm{.}168\mathrm{.}20\mathrm{.}10$

Assign the last usable IP on

Assign the second usable IP on

Explain why those are the second usable IP address and the last usable IP address.

$-$ Use the network $192\mathrm{.}168\mathrm{.}30\mathrm{.}0/24$ to connect and

The gateway IP is: $192\mathrm{.}168\mathrm{.}30\mathrm{.}10$

Assign the first usable IP on

Assign the last usable IP on

$-$ Use network $192\mathrm{.}168\mathrm{.}40\mathrm{.}0/24$ to connect $,$ and

The gateway IP is: $192\mathrm{.}168\mathrm{.}40\mathrm{.}10$

Assign the second usable IP on

Assign the first usable IP on after assigning IP of

Assign the last usable IP on

$-$ Use the network $172\mathrm{.}78\mathrm{.}30\mathrm{.}0$ for the router and assign the first usable IP to R and select the appropriate mask for this network.

Ping from to $,$ to and to $.$ Provide all screenshots from the ping. Time and TTL should be visible in the screenshot.
