create a packet tracer file based on the following discription: I could only describe how we represent this network design in Packet Tracer below.

Core Layer:

Place $2-3$ core routers for redundancy

Configure OSPF or EIGRP for dynamic routing

Implement router redundancy with HSRP or VRRP

Distribution Layer:

Add multiple Layer $3$ switches

Configure VLANs for traffic segmentation

Set up inter$-$VLAN routing

Access Layer:

Add Layer $2$ switches for end$-$device connectivity

Connect Wireless APs to these switches

Security Devices:

Place firewalls between the core and distribution layers

Add an IDS$/$IPS appliance

Servers:

Add a RADIUS server for authentication

Include a DHCP and DNS server

Wireless:

Add a wireless controller

Connect multiple APs to simulate campus$-$wide coverage

External Connectivity:

Include a simulated ISP connection

Add the communication tower for external user connectivity

End Devices:

Add various end devices $($PCs$,$ laptops, smartphones$)$ to simulate users

Configuration:

Configure IP addressing schemes for all devices

Set up VLANs on switches

Configure wireless networks with appropriate security settings

Implement ACLs on routers and switches

Set up RADIUS authentication

Configure QoS policies

Testing:

Use Packet Tracer's simulation mode to test connectivity between devices

Verify that devices can ping each other as required

$1$st step:

The Packet Tracer file design involves core routers with the use of dynamic routing and therefore redundancy. In addition, there are some Layer $3$ switches used for VLAN segmentations and inter$-$VLAN routing, and there are some Layer $2$ switches used to connect the end devices. Wireless APs will be attached to them, while the wireless controller will be used for campus$-$wide coverage. As for security, firewalls, IDS$/$IPS appliances, and a RADIUS server will handle the authentication. Configuration will include DHCP and DNS servers, simulated ISP connectivity using CS$,$ as well as a communication tower. The configuration will then go ahead to set IP addressing, VLANs, wireless security, ACLs, RADIUS Authentication, and QoS policies. Lastly, testing of the end$-$to$-$end connectivity is done to verify that all devices can ping each other.
