| 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. |

| |
| 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. |
