VLAN entire organization
Hi, I am in the process of putting together a VLAN plan for entire organization located in 5 different locations.
I am thinking of using VLAN segmentation 172.22.x.x/19 subnets. Could I use this across entire organization at different sites?
This is what I initualy planned for one site, however now I am planning all 5 sites. I have about 1000 devices per site.
Something like this below but I'd like to change to 172.22.x.x/19. What would that look like?
Thank you so much!

I apologize, yes I'm looking for subnetting help. The different sites will be routing between each other, so why couldn't I use the same \19?
So each site will use the same VLAN numbering scheme?
How many devices on each VLAN at each location?

I'd say I have no more then 1000 devices at each location. I figured I do each location within my 172.22.X.X /19.

172.22.0.1 - 172.22.31.254 would be one location and I'd VLAN that range for all devices listed. Does that make sense?
Yep. Sounds like a plan.
and the other locations would be something like 172.23.0.0, 172.24.0.0, etc.?
and the other locations would be something like 172.23.0.0, 172.24.0.0, etc.?
ASKER
yes. then could I VLAN within that range for all my listed devices? The only issue I see is would I be able to route to other locations this way?
Yes and yes.
ASKER
Thank you!
I am thinking of using VLAN segmentation 172.22.x.x/19 subnets. Could I use this across entire organization at different sites?Yes you can do that, since each site has it's own router, but I suggest to use different subnets
For example in site 1 use 172.31....
In site 2 172.16.....
site 3 192.168..
in site 4 10.10....
And so on, in that case it's easy to remember each site subnet and less subnet conflict between the site, less routing issue (for example advertising a fault subnet).

Hi Elie, thank you. Do you know of a tool that will expand each Useable IP by subnet in an excel spreadsheet? a subnet calculator provides the range details but doesn't list out all IPs.
The good tools are paid, one of the best in IPAM which discover the network automatically.
I Suggest to create a excel sheet for each site and add the subnet.
As for the subnetting you can use any online subnet calculator.

Advance Subnet Calculator worked pretty good for me and I copied/paste into Excel.
I believe I am not explaining correctly, and I apologize. What I am wanting to do if possible is use 172.22.x.x/19 for entire organization.
For VLANS: I'd use
172.22.0.1 - 172.22.0.254 VLAN #1
172.22.1.1 - 172.22.1.254 VLAN #2
...and so on until I reach all VLANs per site
Then for site #2 I'd start with 172.22.10.0 and set VLANS 172.22.10.1 - 172.22.10.254 VLAN 1and again all the way until I hit all VLANS for that location. Then next site 172.22.20.0. Hope this makes sense. It does in my brain. Again, I am sorry if this doesn't make sense.

Yes, it would work. You have 13 bits to work with. 3 bits for the 5 different sites would leave you with 10 bits which would accommodate 1022 hosts per site.

Even if i need to route between sites?

We are connected via SDWAN.
Are those links to be addressed within the 172.22.0.0 address space?
ASKER
Yes, I believe so.
Then you would need to use one of the address ranges for those as well.

Ok, last question...thank you so much for your help. Now, I want to setup VLANs. Would it look something like this below? How would I VLAN within each site subnet 172.22.0.0, 172.22.32.0, 172.22.64.0, 172.22.96.0?
If that's correct, your 5 sites will be addressed 172.22.0.0, 172.22.32.0, 172.22.64.0, 172.22.96.0 and 172.22.128.0 all with a /19 mask. That will allow 8190 hosts per site.

I don't understand the question. Do you want subnetting help?
