vlans in packettracer exclude 1 department

[ajf84]

guys,

lets say, i got 3 departments, 2 switches and 1 router. Normally i would use trunk to add the vlans so they can communicate with eachother and connect to servers. But what if i dont want that. What if i want one department to connect only to the servers and to the Internet, but not to the other departments? How should i configure that? 

Hope this makes sense

You would use access lists on the L3 interfaces for the vlans.

not sure what you you looking for:-

But if you want to pass specific vlan traffic from the trunk port, you can configure allow VLAN command on the port.

Please share the zip your packet tracer project.

Thanks,

Hi

  Actually the topology does not change much between a scenario where vlans inter-communicate and a scenario where vlans does not inter-communicate. What you can use ACL to isolate vlans or you can use Private vlans, if the switch supports it.
