Vlan IDs

Hi,

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)

Regards

Kim

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
