Dual-Router VLAN Topology Examples
Dual-router VLAN topologies combine redundancy and network segmentation to keep critical services running. These examples illustrate how to design VLANs for IoT devices, production floors, retail environments, and high-availability setups—all with a second router for failover.
Describe it in plain English — the AI drafts it, you edit. No template wrangling.
About these examples.
Whether you're a network engineer planning a greenfield deployment or an IT architect documenting an existing network, these diagrams provide a clear starting point. Each shows router placement, VLAN-aware switches, and interlink paths tailored to common scenarios.
No drawing skills required: use our built‑in generator to describe your own dual-router VLAN diagram and get a polished result instantly.
Make one yourself.
Define VLANs and subnets
List the VLANs you need (e.g., management, production, IoT, guest) and assign IP ranges. This is the logical blueprint for your topology.
Place routers and switches
Add two routers for redundancy and at least one VLAN-capable switch. Position them where they best serve your physical or logical layout.
Draw trunk and access links
Connect routers to switches with trunk links carrying all VLANs. Attach endpoints to switch ports in their respective VLANs.
Label and color-code
Use distinct colors or labels for each VLAN and highlight failover paths (e.g., HSRP/VRRP). This makes the diagram self-explaining.
Generate and export
Describe your final topology in the generator, let it auto-layout, then download as PNG or copy the embed code for your documentation.
