Wireless Roaming

[titusgateri]

Hello,

Having gone through the Enterprise Mobility 4.1 Design Guide, I understand there are several types of roaming options:

• Layer 2 roaming (within 1 or multiple WLCs)
• Layer 3 roaming (multiple WLCs)

I wanted to find out if Layer 3 roaming (APs in different subnets) can be achieved with one WLC. I have not been able to find documentation about this.

Thx,

Titus

Hi Titus,

The answer  to your question is yes.  With L3 roaming, all of the client traffic is sent back to the wireless controller inside the CAPWAP tunnel. From the network’s standpoint, the client’s traffic is anchored at the controller regardless of what subnet the AP is on and the APs will simply route to the controller.

I hope this helps.
