Configure branch office VLANs to route across WAN

If your traffic isn't routable across WLAN networks, learn how you need to configure your branch office VLANs to route traffic across your WAN.

I am getting ready to deploy a wireless VLAN at all of my branch offices that will actually access a secondary Internet connection from my central office. All of my branch offices are running Cisco 3500 series switches, and my downtown branch is on a 4510. How do I configure the VLANs at the branch offices to route across the WAN if the traffic isn't routable across the WLAN networks? Do I need to build additional virtual interfaces? I want this traffic to remain segregated from my normal LAN/WAN traffic.

You need to implement inter-VLAN routing across the locations. You can also do bridging, but I would not recommend it, as it might choke your WAN links.

Hope this helps.
