If your VLAN is small then your exposure is huge, if your VLAN is big, then your exposure is mega-super-huge (I have customers whose whole corporate network is a huge VLAN, but that´s another issue). Then you have attacks to the stability of your LAN through the use and abuse of the Spanning Tree Protocol (yersinia is the de-facto tool for this).

VRFs, VLANs and subnets: difference - Network Engineering IP subnets and VLANs are not mutually exclusive -- you don't choose one or the other. It most cases, there is a one-to-one correspondence between VLANs and subnets. In your first example, assuming you're using IP, you are still going to have to assign IP subnets to the VLANs. So you would assign a separate IP subnet to VLAN 1 and 2. VLAN VS PRIVATE VLAN - IP With Ease 1. Different Vlans must belong to different IP subnets. PVLANs belong to the same IP subnet. 2. Vlan works in Layer 2 and Layer 3. PVLAN is method to segment device at layer 2. 3. Vlan is the basic requirement for all LAN. Environments. VLAN VS SUBNET - Know the difference in VLAN & SUBNET - IP VLAN SUBNET; Philosophy: VLAN is a logical local area network that contains broadcasts within itself and only hosts that belong to that VLAN will see those broadcasts. Subnet is an IP address range of IP addresses that help hosts communicate over layer 3. Logical and Physical Networks: VLANs allow us to create different logical and physical VLANs & VPNs: pfSense Segmented Routing

Tunnels, VPNs, and VLANs

VPN Business Router with InterVLAN routing, Support for QoS and 802.1q VLANs (256) VLAN in VLAN support (QinQ) for private VLAN tagging in ISP network for an additional layer of isolation and security; VPN with SSL Encryption (DES, 3DES, AES) REMOTE MONITORING AND MANAGEMENT FROM NETGEAR INSIGHT Jul 20, 2018 · VPLS (Virtual Private LAN Service) is a service that uses MPLS and VPN (Virtual Private Networking) to securely and seamlessly connect multiple LANs over the Internet, making them appear as if they were all on the same LAN.

It looks like the route will do simple QoS based on the port (e.g., one LAN port can be "high" priority and the others can be "normal"). I think I can connect one "normal" LAN port to a port on the switch used in the Data VLAN and another "high" priority LAN port to a port on the switch used in the VOIP VLAN to prioritize voice traffic.
