OK so a physical subnetted network is 'safer'/'more secure'
than a VLAN network.
I'm still not getting the difference between a virtual and a
physical LAN. Can anyone give me an example of say a company
with two branches in different locations with each branch
have its own sales and accounts department. I would subnet my IP such:
Office A 192.168.0.x
Office B 192.168.1.x
The departments of each office would have IP's from their
respective subnet.
Sales A 192.168.0.1
Sales B 192.168.1.1
Accounts A 192.168.0.2
Accounts B 192.168.1.2
Make sense?
tnx for the help
Different locations? Then you want two physical LANs, each with
their own address block, and you might use a third (tiny) block
to manage the WAN link between locations.
Where you would use VLANs is to separate different departments
(or organizational units or security contexts) *in the same
physical vicinity*. Instead of mounting two adjacent devices
(physical), you install a single device and ("logically") partition
it (virtual).
so, in the example above although I might have 2 physical LANs I could
also have 2 VLANS, one for sales and one for accounts?
