Independent VLAN within a routed network

Hi, can you guys help me about a tasks I am trying to achieve.

So say we have a normal cisco router connected to an L3 switch which then holds all my InterVLAN gateway. All VLANS can access each other. (thru OSPF)

What I would like to do is create a special lonely VLAN, that can only access the router and internet and will not be able to see the othet VLANS. Is this possible?

Hello Kyle

Yes, this is something that is possible. One possibility is to use access lists to block or allow whatever traffic you’d like between the VLANs. Another more elegant solution is the use of private VLANs. More about these and how to configure them can be found here:

I hope this has been helpful!!
