WLC one WLAN, multiple subnets

[csocorro1]

Good afternoon,

Is it possible to have one WLAN associate to multiple networks? I configured 2 WLANs, Local and Guest.

This is the situation:

I have a Central Office where the WLC is located and with its own DHCP server. It has VLAN 21 and 22. They have the following addressing:

VLAN 21 - Local: 10.10.21.0/24

VLAN 22 - Guest: 10.10.22.0/24

There are four branch offices with the same VLANs but with thier own DHCP servers. For example:

Branch 1: 

VLAN 21 - Local: 10.15.21.0/24

VLAN 22 - Guest: 10.15.22.0/24

Branch 2: ........

Is it possible that one WLAN have more than one interface and the WLC identify where is the user trying to connect, so it can lease an IP from the network of each branch site? Or just with one interface assign an address that belongs to different subnets?

I would go with FlexConnect for the remote sites.

Steve thank you for your short response.

I alredy configured branch APs with the FlexConnect mode and the clients are still receiving Central Office subnet addresses, even when each Branch have their own DHCP Servers.

Do you have an idea of what can be happening? 

Is it maybe because I have to configure to each WLAN an interface pointing to every branch DHCP server?

I really appreciate your help.

So the WLAN is enabled for FlexConnect local switching, and you went into the AP and mapped the VLAN?
