WIreless Network Extension

[netbeginner]

HI Experts, We are stuck with a new requirement. We have two separate locations independent of each other , One location is Data Center and other is Technical Support Center. As mentioned above, Technical Support Center(TSC) is not having any dependency on Data Center for running it's Wireless LAN services. TSC is having own SAP (standalone access points) with locallized VLANs. New Requirement : Plan is to make Wireless Central Controller from Data Center for TSC, for this a Controller appliance is also planned to deploy at Data Center. all the SAP at TSC then has be convert to Light Weight access point Problem : Scenario is - TSC LAN Network --> TSC Router ---> Point-to-Point Link <-- Data Center Router <-- Data Center Firewall <---Data Center Core Swicth (Wireless Controller should be deploy somewhere here). We have to extend all TSC network Pools at Data Center Center, but in between these we have three Layer-3 devices comes between i.e. TSC router, DC Router, DC Firewall which is somehow a show stopper. Requesting to suggest solution. Rgds ***

Once you convert to LAP, then that AP act as another AP on your DC site. So users will get IP from DC switch where you connect your WLC.

This is called Local Mode AP deployment.

If you really want to keep wireless user traffic terminate at TSC, you can do that as well. This mode is called FlexConnect, where only AP control traffic come to WLC, where as data traffic terminate at locally in a branch. Read below design guide on FlexConnect

Hi Rasika, Thanks ! But here in our scenario WAN will be involved between Data Center and TSC. guess this require REAP/H-REAP compatible Access points.

As long as that WAN connection is secure (ie not over public internet), you can still run local mode at the other side without majour issue. 

Disadvantage is even two wireless users communicate at TSC site, that traffic has to go through your central WLC at DC (hair pinning across your WAN link). If you have limited bandwidth, I would go with FlexConnect. If bandwidth is not an issue, local mode would simplify the deployment
