With the launch of mobile devices in 2007, the use of Wi-Fi increased exponentially. To support increased number of clients on wireless Local Area Network (WLAN), network administrators started adding more VLANs with smaller subnet size for wireless clients, and VLAN Pooling became popular concept. Today, the requirement from WLAN has changed quite a bit compared to a decade ago. Increased use of IPv6 and large number of mobile devices roaming across the campus has increased the complexity of WLAN design.   

 

Rather than using conventional design with VLAN Pooling and multiple smaller subnets, we think that there is a better way to design WLAN today using “Single VLAN with One Large Subnet" to serve all the wireless clients connecting to an SSID. This paper explains how we came to this conclusion
