Fabric Enabled WLC:
Fabric enabled WLC is integrated with LISP control plane. This WLC is responsible for AP image /Config, Radio Resource Management, Client Session management and roaming and all other wireless control plane functions.
For WLC Fabric Integration:
Wireless Client MAC address is used as EID
It inform about Wireless MAC address with its other information like SGT and Virtual Network Information
VN information is mapped to VLAN on FEs
WLC is responsible for updating Host Database tracking DB with roaming information

There are five basic device roles in the fabric overlay:
+ Control plane node: This node contains the settings, protocols, and mapping tables to provide
the endpoint-to-location (EID-to-RLOC) mapping system for
the fabric overlay.
+ Fabric border node: This fabric device (for example, core layer device) connects external Layer
3 networks to the SDA fabric.
+ Fabric edge node: This fabric device (for example, access or distribution layer device) connects
wired endpoints to the SDA fabric.
+ Fabric WLAN controller (WLC): This fabric device connects APs and wireless endpoints to the
SDA fabric.
+ Intermediate nodes: These are intermediate routers or extended switches that do not provide
any sort of SD-Access fabric role other than underlay services.
