Does my router need to support VLAN?
Must I use untagged VLANs in order for it to work? Yes… but that won’t make it work. If the device (router) doesn’t support VLANs, that usually means it won’t understand any 802.1Q tagged packets, therefore its switch port must have one untagged VLAN (and the port’s PVID must match).
Do you need a router to create a VLAN?
VLANs don’t need routers to communicate. Well, they usually do, but not necessarily. They just need some “external help”.
Why VLAN is used in router?
VLANs free up bandwidth by limiting node-to-node and broadcast traffic throughout the network. VLANs enhance network security. VLANs create virtual boundaries that can be crossed only through a router. Therefore, you can use standard, router-based security measures to restrict access to a VLAN.
When should you use a VLAN?
A VLAN allows different computers and devices to be connected virtually to each other as if they were in a LAN sharing a single broadcast domain. A VLAN is helpful for organizational use mainly because it can be used to segment a larger network into smaller segments.
Which is better VLAN or subnet?
VLANs perceived to be more secure and provide more robust control for the network. Subnet has limited control in comparison to VLAN. VLAN is extremely flexible, it brings better work performance, less traffic, and more efficiency.
What are the disadvantages of VLANs?
Disadvantages of VLAN
- A packet can leak from one VLAN to other.
- An injected packet may lead to a cyber-attack.

What is a VLAN and how do I use it?
VLANs can also be used to enhance performance by reducing the need to send broadcasts and multicasts to unnecessary destinations. You can create a VLAN, but this has no effect until the VLAN is attached to at least one port, either manually or dynamically.
