+Supported Topology
+******************
+
+Trellis supports various topologies, from a single switch to a full multi-stage leaf-spine fabric.
+
+Simple
+======
+
+Single switch
+-------------
+This is the minimum Trellis setup. In this setup, all servers are connected to a single switch.
+

+
+Paired switches
+---------------
+Compared to single switch, it provides more redundancy in terms of server NIC failure and link failure.

+
+Single-Stage Leaf-Spine
+=======================
+
+Without paired switches
+-----------------------
+Compared to single switch, it offers more redundancy in terms of switch failure and provides better scalability.
+
+    .. image:: images/install-2x2.png
+
+With paired switches
+--------------------
+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.
