Lab 1: Networking Fundamentals Lab Topology

Overall Network Overview:

The networking fundamentals lab course is a detailed, step‐by‐step series of labs designed specifically for beginners. These labs are organized into two sites and include real-world scenarios, explicit configuration commands, verification steps with expected outputs, and even a couple of automation labs at the end. 

In this design, Site 1 uses a Cisco router R1 as the DHCP server. Also, note that the static routes are placed for inter-site connectivity. NAT is used on both site routers to provide secure internet access. SW1 will also be used for webserver that will be accessed from site 2.

Site 1:

● LAN Subnet: 192.168.1.0/24

● R1 (Cisco): LAN IP 192.168.1.1/24; WAN IP 203.0.113.1/30

● SW1 (Cisco): Configured with VLAN 20 for Data

● LnxPC1: IP 192.168.1.10/24

● WindowsPC1: IP 192.168.1.20/24

● DHCP Server: Provided by R1

Site 2:

● LAN Subnet: 192.168.2.0/24

● R2 (Cisco): LAN IP 192.168.2.1/24; WAN IP 203.0.113.2/30

● SW2 (Cisco): Also configured with VLAN 20 (Data)

● LnxPC2: IP 192.168.2.10/24 

● WindowsPC2: IP 192.168.2.20/24

Both sites connect via a simulated Internet “cloud” through their WAN interfaces. Static routes are used to enable inter-site connectivity.
