That was only to show which VLAN's I assigned which layer 3 addresses for...
Thanks,

I have one problem with this scenario:
Why did you put VLAN under layer 3 info?
As far as I know they are strictly L2
My two cents:
Assuming that they have their own servers, and that you are not routing
between them
then they can have any address that you wish (private). It is like having
two LANs.
The switches can also be totally separate.

Subject: BCMSN: VLAN's and Subnets
I have a question about implementing VLAN's in existing LAN's.
Let's say that I have one office with stacked switches connecting 100 users
to a network with a couple of servers and other good stuff.
Layer 2 info : Ethernet, one big broadcast domain
Layer 3 info : IP, one full class C : 192.168.16.0
After having analyzed the entire LAN, I find out that 50 users are using
resources that the other 50 users are not using, and the same thing the
other way around. Instead of splitting the stacked switches up in two
separated physical stacks, I now assign the ports for the first 50 users to
VLAN 11 and for the rest 50 users VLAN 12.
Layer 2 info : Ethernet, two big broadcast domains (not including
VLAN1)
Layer 3 info : IP, one full class C : 192.168.16.0
I would assume that this would work great as long as noone from VLAN 11
needs any resources from VLAN 12, and the same thing the other way around.
Now to my question (which is more a confirmation of my theory):
I would only need to split my class C up in subnets if I want Inter-VLAN
communication between my VLAN 11 and VLAN 12 right???
Layer 2 info : Ethernet, two big broadcast domains (not including
VLAN1)
Layer 3 info : IP, VLAN 11 : 192.168.16.64/26, VLAN 12 :
192.168.16.128/26
Do I have the right idea, or am I way off???
Thanks for your comments on this.
Ole
