Vlan IDs


We currently have a main site with multiple Vlan's.  For example

10 MGMT (10.x.x.x)
20 Users (10.x.x.x)
30 Servers (10.x.x.x)
40 WIFI (10.x.x.x)

This has a 10.x.x.x IP Address Range.

I want to setup a second site connected via a Cisco ASA VPN

The second site will have the 172.16.x.x address range

Question ?

Is the any reason or concerns why I cannot use the same VLAN ID's at the second site with the 172.16.x.x addressing

10 MGMT (172.16.x.x)
20 Users (172.16x.x)
30 Servers (172.16.x.x)
40 WIFI (172.16.x.x)

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can surely use the same vlan ids on the second site .Because it will be different layer 2 domain. Once the two switch domains are separated by a layer 3 domain you can re use the same vlan ids. In your case , because both subnets are different so routing will be  involved and you can reuse those same vlans.

Hope this helps.

can't see any issues as they are 2 separate physical sites and don't talk to each other without routing / configuration. Make sure its fully documented as a best practice
I agree no issues.  If you want to understand it more here is a great little article.
