v1.0 - Initial CCNA Wireless study topology

Introduction

This is the initial version of the network topology, specially crafted for testing wireless and studying the CCNA Wireless certification. The network is meant to be future proof (CCNP Wireless is coming in early 2026) and modular.

Although built with wireless in mind, the network can be easily adapted to test VoIP (CCNA Voice/Collaboration) and security (CCNA Security) labs. Obviously, also routing and switching (CCNA / CCNP Enterprise Core).

Scenario and Notes

The topology depicts the network of a fictional enterprise I will use throughout the labs, called Jimenez Research Incorporated. 

Initially, I will divide the network in two offices, the Madrid office and Leon office.

  • Each office will have an L2 switch (LAN.MAD.01, LAN.LE.01). They will act as the offices' main switch (and also in this initial version, the only).
  • On both offices, the switches will connect 2 APs and one laptop, each in their respective subnets/VLANs.
  • Two WLCs, one on each office, in HA SSO mode.
  • Internet connection will be provided by DIGI (provider I have at home).
  • Routing is handled by OPNsense, running as a VM in Proxmox. Proxmox itself is installed in a miniPC.
  • Depicted in the topology is also a management PC on a separated VLAN, from which I will operate the network.
  • The edge switch (an L2 switch actually) called JRI.EDGE will serve the connection to both offices and connect them to the miniPC.
  • The TP-LINK switch is necessary due to how my home is networked (PoE stuff, etc).
