- Which physical devices support the lab
- How eight virtual sites map onto the hardware
- Why the topology remains vendor-neutral
The physical lab will consist of a Dell Inspiron 15 laptop connected wirelessly (via Wi-Fi) to my Internet Service Provider (ISP) wireless router. Wired connections will run from the ISP router to the Lenovo P720 workstation and the Juniper EX-2200 switch, as per our topology illustrated below.

Runs the virtual labThe virtual lab will comprise 8 sites, including 6 Remote Branch offices and 2 Data Centers (Head Quarters) buildings, as depicted below. These labs will maintain a vendor-neutral focus. Whenever possible, we will integrate a variety of vendor equipment and tools to foster a diverse lab environment. Thus, the topology for the lab will continually evolve and be updated on our GitHub page.

With the topologies now ready, our next post will cover the naming conventions, subnets, and IP addressing for each site. Understanding these elements is key to a consistent lab environment, and we're excited to share our approach and insights in upcoming blogs.
