 Single Leaf (ToR)
 -----------------
 This is the minimum SD-Fabric setup. In this setup, all servers are connected to a single switch.

-Paired Leaf (Dual-Homing)
--------------------------
+Single Leaf Pair (Dual-Homing)
+------------------------------
 Compared to single switch, it provides more redundancy in terms of server NIC failure and link failure.

 Leaf-Spine (without pairing)
 ----------------------------
 Compared to single switch, it offers more redundancy in terms of switch failure and provides better scalability.

 Leaf-Spine (with pairing)
 -------------------------
 It supports all the redundancy and scalability features mentioned above.

 Multi-Stage Leaf-Spine
 ----------------------
 Multi-stage is specifically designed for telco service providers.
-The first stage can be installed in the central office,
-while the second stage can be installed in a field office that is closer to the subscribers.

 Two stages are typically connected via long distance optical transport.
