Solution
The Meru technology has a concept of Virtual cell & Vport.
Virtual cell means that the BSS will be shared by a common BSSID for an ESS for a particular SSID, which is broadcasted by all the AP's on the network.
Virtual port means for each client connecting to the WLAN, there will be a separate BSSID generated by the AP and broadcasted by that particular AP on which the client is connected.
When one client is connected to an AP, there will be a parent beacon (with Parent BSSID) for that SSID and also there will a CSSID beacon (with child BSSID) broadcasted by the AP. From the Insider perspective, it will see two different BSSID's now with the same SSID name.
