Dynamic ARP Inspection | Packet Tracer Lab

In this video I configure R1 as a DHCP server and implement essential security measures to protect the network from spoofing attacks using Cisco Packet Tracer. After setting up the DHCP pool and excluding reserved addresses, I enable DHCP snooping on SW1 and SW2 to prevent unauthorized DHCP responses. I then configure Dynamic ARP Inspection (DAI) on both switches, activate all validation checks, and mark trusted ports appropriately. This lab provides a hands-on look at DHCP infrastructure hardening and helps reinforce best practices in securing Layer 2 networks.
