Design a logical network topology using Packet Tracer simulation software for the company described in the scenario below.

Important:$$ Read and understand each of the design requirements to ensure that your design is accurate.

A local hardware company has recently expanded its operations and has asked you to design and implement a network to meet its needs. The company consists of a headquarters, two other sites and a data centre. For security reasons, the company wants to use private addresses throughout, as well as DHCP for the LANs. Due to the size and complexity of the company, they want to create VLANs to control broadcasts, enhance security and logically group users.

You have been asked to provide a logical topology diagram as a proof of concept of the network you wish to build

Design Requirements

$1.$ Follow a logical and appropriate naming convention for the device names, site names, LAN names, usernames and domain names.

$2.$ Network requirements and Subnetting guidelines.

$$ The company appreciates efficiency and addresses conservation in design. To minimize wasted address space, they have requested that VLSM $($variable length subnet masks$)$ be used when appropriate, and each site must summarize its LANs to reduce routing table entries and enhance stability.

$$ For scalability and performance, the company also wants to implement a three$-$tier hierarchical network architecture.

o$$ Headquarters is Site $1,$ and the other two sites are connected to Site $1$ through core switches.

o$$ Site $1$ needs redundant gateways, so HSRP will be used.

o$$ The data center distribution switch is also connected to the core switches.

$$ The data centre includes:

o$10$ servers, including a DHCP server to provide IP addresses for all hosts in all sites, a RADIUS server to authenticate wireless devices and clients, an FTP server and web servers, and others.

o$$ Wireless LAN controller that supports two wireless LANs with $100$ users each.

$$ The company wants to implement EIGRP in Site $2,$ the rest of the sites use OSPF. The core switches in Site $1$ are connected to an edge router for internet connectivity.

$$ Except for the connectivity between ALS and DLS switches, all interconnections are L$3$ connectivity. You need to provide redundancy as needed.

$$ All devices must have an IP address.

o$$ Expect $50\%$ growth of current IP requirements when determining the size of the subnets.

o$$ Use $10\mathrm{.}69\mathrm{.}0\mathrm{.}0/16$ for internal addressing.

o$$ Make sure the summary address is calculated for each site based on the subnets assigned for the LANs on the site.

o$$ Use $/30$ subnets for the layer $3$ links and all the WAN interfaces.

o$$ Assign names to all devices as per your naming convention.

o$$ Connect the edge router to the ISP router using subnet $200\mathrm{.}200\mathrm{.}200\mathrm{.}0/30.$ The ISP server attached to the ISP router provides DNS$,$ website and NTP services using subnet $200\mathrm{.}200\mathrm{.}200\mathrm{.}8/29.$

o$$ Define VLANs, names and their network addresses.

o$$ The DHCP server should be kept in the data centre, and IP helper addresses need to be configured.

o$$ Configure at least one host to each LAN.

$$ Create a subnetting and summarization table for each site, showing the subnets for each LAN, usable IP range, and the summary address for the site.

Site name

Subnet name

Subnet address

Subnet mask

$1$st usable address

last usable address

Broadcast address

Summary address

$$ Site $1$

Lan $1$

Lan $2$

Lan $3$

Lan $4$

$$ Create an addressing table based on your network topology. The addressing table will assist with design and development activities and is critical when configuring switches and routers. It should include all the devices, including routers, switches, PCs and servers. A sample layout is provided below.

Addressing Table

Device Name

Interface

IP Address

Subnet Mask

Gateway

$$ Create a DHCP table with a pool name, network address, subnet mask, gateway, DNS server, domain name and list of excluded addresses for servers and gateways in each LAN for all the sites. A sample layout is provided below.

DHCP Table

Pool Name

Network Address

Subnet Mask

Default Gateway

DNS Server

Domain Name

Excluded address

$$ Create a WLAN table for employee and guest WLANs with SSID, username and password. For example

WLAN Name

SSID

Authentication

Username

Password

Employee

$$

WPA$2-$Enterprise

$$

Guest

$$

WPA$2-$PSK
