| 4 | Trellis supports various topologies, from a single switch to a full multi-stage leaf-spine fabric. |
| 5 | |
| 6 | Simple |
| 7 | ====== |
| 8 | |
| 9 | Single switch |
| 10 | ------------- |
| 11 | This is the minimum Trellis setup. In this setup, all servers are connected to a single switch. |

| 14 | |
| 15 | Paired switches |
| 16 | --------------- |
| 17 | Compared to single switch, it provides more redundancy in terms of server NIC failure and link failure. |

| 21 | Single-Stage Leaf-Spine |
| 22 | ======================= |
| 23 | |
| 24 | Without paired switches |
| 25 | ----------------------- |
| 26 | Compared to single switch, it offers more redundancy in terms of switch failure and provides better scalability. |

| 29 | |
| 30 | With paired switches |
| 31 | -------------------- |
| 32 | It supports all the redundancy and scalability features mentioned above. |

| 35 | |
| 36 | Multi-Stage Leaf-Spine |
| 37 | ====================== |
| 38 | Multi-stage is specifically designed for telco service providers. |
| 39 | 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. |
| 40 | Two stages are typically connected via long distance optical transport. |
