QUESTION POSED ON: 08 October 2007

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.

EXPERT RESPONSE

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.
