We lost the configuration we had on our WLC 5508 controller and had to start from scratch. Now we are trying to figure out how to properly configure everything. Right now we are on software version 18.104.22.168.
Here is our topology:
- We have 7 sites with APs.
- Each site uses the same vlans, but different subnets.
VLAN 100 - DATA - 10.1.100.0/24
VLAN 200 - VOICE - 10.1.200.0/24
VLAN 300 - WIRELESS APs - 10.1.300.0/24
VLAN 400 - GUEST NETWORK - 10.1.400.0/24
VLAN 100 - DATA - 10.2.100.0/24
VLAN 200 - VOICE - 10.2.200.0/24
VLAN 300 - WIRELESS APs - 10.2.300.0/24
VLAN 400 - GUEST NETWORK - 10.2.400.0/24
All subnets default gateway to a router local at each site which handles DHCP for all local VLANs, and those routers talk via MetroEthernet to Site 1 where the WLC resides. The WLC has a management address outside the 10.x.x.x range and everything is routed accordingly.
I know we had FlexConnect groups configured before for each site, but from my reading, it sounds like having the same VLAN numbers at each site will hinder the FlexConnect configuration and cause confusion if multiple FlexConnect groups are configured with the same VLAN numbers but use different subnets. Is this true?
Given this topology, what is the best way to configure the WLC? Is FlexConnect the way to go? If so, Should the FlexConnect Group WLAN VLAN Mappings be configured a certain way?
